Get value from directive to $scope in controller

In my Directive, I've getting some data from my backend like this:

var monster_info = angular.element(this).find("img").attr("title");
                    $http.get("lib/terrain.php", {params: { monster_data:monster_info}}).success(function(data) {
                            console.log(data);
                    });

I want this data to appear at my site, so I've tried to declare a variable like this in my controller: $scope.fish = [];

Then I just assign the data value like this in my directive: $scope.fish = data;

But nothing is printed out. How does the communication between controller and directive work? How should I share this kind of data?

Here is my whole directive:

angular.module('gameApp_directives').
  directive('mapActivity', function($http) {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            scope.$watch('tabledata', function() {

             angular.element('.click#1').addClass('dotted').html($("<img src='images/dot.png'>"));          
                var j = null;
                for(var i = 1; i <= 4; i++)
                {
                    $.ajax({
                        type: 'GET',
                        url: 'lib/terrain.php',
                        dataType: 'html',
                        data: {i: i},
                        success: function(data) {
                            var randomRuta = Math.floor((Math.random() * 100) + 1);
                            angular.element('.click#'+randomRuta).addClass('monster').html($("<img src='images/blackdot.png' title='"+data+"'>"));                  
                        },
                        error: function(xhr, ajaxOptions, thrownError) { alert(thrownError); }
                    });
                    j=i;
                }  
                angular.element('.click').click(function() {
                    if(angular.element(this).hasClass('monster'))
                    {
                        var monster_info = angular.element(this).find("img").attr("title");
                        $http.get("lib/terrain.php", {params: { monster_data:monster_info}}).success(function(data) {
                                console.log(data);
                        });



                        /*if(confirm('Vill du anfalla monster?'))
                        {
                            alert("Du vann");
                            angular.element('.click.monster'+j).empty();
                            angular.element('.click.monster').removeClass('monster'+j);

                            angular.element('.click.dotted').empty();
                            angular.element('.click.dotted').removeClass('dotted');
                            angular.element(this).addClass('dotted');
                            angular.element('.click.dotted').html($('<img src="images/dot.png">'));
                        }*/
                    }
                    else
                    {
                        angular.element('.click.dotted').empty();
                        angular.element('.click.dotted').removeClass('dotted');

                        if(!angular.element(this).hasClass('dotted'))
                        {
                            angular.element(this).addClass('dotted');
                            angular.element(this).html($('<img src="images/dot.png">'));
                        }
                    }
                });
            });                     
        }
    };
});

Here is my controller:

angular.module('gameApp_controllers')
    .controller('gameCtrl', ['$scope', '$http', '$location', '$sce', '$rootScope', 'link', function($scope, $http, $location, $sce, $rootScope, link) {

        $scope.resultLoaded = false;
        $scope.getMonsters = "1";
        var tabledata = ""; //Variable to store pattern for html table

        $http.post("lib/action.php", {monsters: $scope.getMonsters}).success(function(data) {   
            //tabledata = data; //Assign the pattern
            $scope.result = makeTableFrom(data); //Call the function to build the table based on the pattern
            $scope.resultLoaded = true;
        }).error(function(data) { console.log("error"); });

        $scope.fish = [];
        $scope.safeHtml = function() {
            return $sce.trustAsHtml($scope.result);
        };


        if(link.user) {
            /*$scope.message = "fisk";
            console.log(link.user);*/
        } else {
        /*$scope.message = "Ledsen fisk";
        console.log("Är inte satt");*/
        }
}]).controller('firstPageCtrl', ['$scope','$http','$location','$sce','$rootScope','link', function($scope, $http, $location, $sce, $rootScope, link) {
        $scope.doLogin = function() {
        $http.post("lib/action.php", {username: $scope.username, password: $scope.password}).success(function(data) {
            if(data) {
                link.user = data;
                console.log(link.user);
                $location.path("/game");
            }
        }).error(function(data) {
            console.log(data);
        });
    };
}]);

Anyone who can help me?

Here is my HTML

<div id="layout_game">
<div ng-controller="gameCtrl">
<div ng-if='resultLoaded' id="rightcontent_game">
    <table ng-bind-html="safeHtml()" map-Activity>
    </table>
</div>

<div id="leftcontent_game">
    <div id="leftcontent_top">
        <ul>
            <li><a href="#">Vildmarken</a></li> <li> | </li> <li><a href="#">Marknaden</a></li> <li> | </li> <li><a href="#">Värdshuset</a></li>
        </ul>
    </div>
    {{fish}}
