MVC and Angularjs : promise does not waiting data - angularjs

Question

i'm newby in angularjs i researched on the internet but i couldn't find any suitable solution for my problem. I made an http call to get some data from controller. The controller side is okay. But the client-side, promise does not waiting data. Here codes that I wrote ;
//service code
angular.module("myApp").service('$myService', function ($http, $q) {
this.getDataArray = function () {
var deferred = $q.defer();
$http.get('../Home/GetDataArray')
.success(function success(response) {
deferred.resolve(response);
})
.error(function () {
console.log("error getting data array");
deferred.reject();
});
return deferred.promise;
};
}
// controller-code
angular.module("myApp").controller('dataController', function ($scope, $http, $myService) {
$scope.getDataFromService = function () {
$myService.getDataArray().then(function (response) {
$scope.dataArray = response.data;
});
};
});
}
When i call the getDataFromService method at first $scope.dataArray is empty, but the second call, $scope.dataArray is filled with data. Where is the problem? Thanks for helps.

Not an angular expert myself. This is just how I did it when I ran into the same problem. Try this:
Controller:
angular.module("myApp").controller('dataController',[ '$scope', 'Service1', '$http', function ($scope, Service1, $http) {
var deferred = Service1.getDataArray().$promise;
return deferred.then(function successCallback(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
$scope.dataArray = response.data;
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
})
}])
and service:
var service = angular.module("myApp").service('myService', ['ngResource']);
myService.factory('Service1', ['$resource',
function ($resource) {
return $resource('../Home/GetDataArray', {}, {
get: { method: 'GET', isArray: true },
});
}])
The idea is that your service isn't the one that should wait for a return, your controller is. So you should wait for the promise in your controller not your service. In my example I am using factories because, well, that's how I got around it in my project, you can try and implement this directly if you don't want to use a factory.
