            hasLiked = true;
            $scope.liked = 'Não Gosto';
            $scope.likeCount += 1;

Data type via socket Allow a function to be called only after a time the page was loaded

Would that be?

EDIT 1

var app = angular.module("App", []);

app.controller("AppController1", function($scope) {
  $scope.varController1 = "JEC nao vai cair!!!";
  $scope.consultarOutroController = function() {
    var scopeOutroController = angular.element('[ng-controller=AppController2]').scope();
    alert(scopeOutroController.varController2);
  };
});

app.controller("AppController2", function($scope) {
  $scope.varController2 = "JEC nasceu campeão!!!";
  $scope.consultarOutroController = function() {
    var scopeOutroController = angular.element('[ng-controller=AppController1]').scope();
    alert(scopeOutroController.varController1);
  };
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<div ng-app="App">
  <div ng-controller="AppController1">
    <input type="button" value="Consultar outro Controlador 1" ng-click="consultarOutroController();" />
  </div>

  <div ng-controller="AppController2">
    <input type="button" value="Consultar outro Controlador 2" ng-click="consultarOutroController();" />
  </div>
</div>

EDIT 2

Another way to share data between controllers is by using $ rootScope. This guy works similarly to a global variable in js.

app.controller("AppController1", function($scope, $rootScope) {
    $rootScope.varController1 = "JEC nasceu campeão!!!";
});

app.controller("AppController2", function($scope, $rootScope) {
    alert($rootScope.varController1);
});

Controller News List

.controller('ListaNoticiasHome', function($scope, $rootScope, $http, $stateParams, $partilharRecursos, sessionService) {
    $http.get("https://www.sabeonde.pt/api/api_noticias_home.php").success(function (data) {
        $scope.noticias_home = data;
    });
    $partilharRecursos.set('idNoticia', '<passe aqui o id>');
});

Controller Like

.controller('LikeNoticiasHome', function($scope, $http, $rootScope, $stateParams, $partilharRecursos, sessionService) {
    var hasLiked = false;
    $scope.like= function (){

        if (!hasLiked) {
            hasLiked = true;
            $scope.liked = 'Não Gosto';
            $scope.likeCount += 1;

            $http.get("https://www.sabeonde.pt/api/api_like_noticias.php?post_id="+ $partilharRecursos.get("idNoticia") + "&user_id=" + sessionService.get('user_id')).success(function (data) {
                $scope.like_noticias_home = data;
            });

        } else {
            hasLiked = false;
            $scope.liked = 'Gosto';
            $scope.likeCount -= 1;

            $http.get("https://www.sabeonde.pt/api/api_unlike_noticias.php?post_id="+ $partilharRecursos.get("idNoticia") + "&user_id=" + sessionService.get('user_id')).success(function (data) {
                $scope.like_noticias_home = data;
            });
        }     
    }
});

Service Sharing Features

.service('$partilharRecursos', function () {
    var property = {};

    return {
        get: function (key) {
            console.log("Key: " + key);
            console.log(property);
            return property[key];
        },
        set: function(key, value) {
            console.log("Key: " + key);
            console.log("Value: " + value);
            property[key] = value;
            console.log(property);
        }
    };
});
