Update $scope with $resource - angularjs

Question

Why is only the one that don't use $resource.get() work? I am using kendo-angular to update. Has this something to do with async? The main variable looks exactly the same so this has to have something to do with $resourse. What am I missing`
This works:
app.controller('SubjectCntrl', ['$scope', 'categoryService', function($scope, categoryService) {
var main = categoryService.getCategories();
var subjects = {
data : [main]
};
$scope.subjects = {
dataSource: subjects
};
}]);
This does not:
app.controller('SubjectCntrl', ['$scope', 'categoryService', 'ApiFactory', function($scope, categoryService, ApiFactory) {
ApiFactory.get(function(categoriesData) {
var main = categoryService.getCategories();
var subjects = {
data : [main]
};
$scope.subjects = {
dataSource: subjects
};
});
}]);
The factory:
app.factory('ApiFactory', ['$resource', function($resource) {
return $resource('http://localhost:8080/rest/forum/categories/1');
}]);
Service:
app.service('categoryService', ['$resource', function($resource){
this.getCategories = function(){
var farmingSubjects = [ {text: "Poteter", spriteCssClass: "subject"}, {text: "Agurk", spriteCssClass: "subject"} ];
var forestSubjects = [ {text: "Tall", spriteCssClass: "subject"}, {text: "Gran", spriteCssClass: "subject"} ];
var animalSubjects = [ {text: "Hundar", spriteCssClass: "subject"}, {text: "Katter", spriteCssClass: "subject"} ];
var farming = { text: "Jordbruk", items: farmingSubjects };
var forest = { text: "Skogshold", items: forestSubjects };
var animals = { text: "Dyrebruk", items: animalSubjects };
var subjects = [farming, forest, animals ];
var main = { text: "Huvudemner", expanded: true, items: subjects};
return main;
};
}]);
Edit: The success function is called without doubt.
ApiFactory.get(function(data){
console.log('success, got data: ', data);
}, function(err){
alert('request failed');
});

I think the second case is not working because you ApiFactory call is failing. The callback you have declared is for success.
