AngularJs server request queue or function is not call

I've subscribed in my controller on socket event. When some event has come, i need to get some data from server (i try to call lb.get() as a function into some factory).

$scope.counter = 0;

$scope.$on('lEvent', function (event, response) { // socket event
                $scope.counter ++;
                console.log('counter '+$scope.counter);

                    var Item = {
                        id: response.id,
                        mime: response.mime,
                        name: response.name,

// here is a function in my factory 

 get: function(id) {
            deferred = $q.defer();
                method: "post",
                url: url,
                data:  $.param({id: id}),
                headers: header
                .success(function (data) {
                .error(function (data) {
            return deferred.promise;

Imagine, i've got 5 socket events, but function lb.get() has called a 4 (or 3) times instead of 5. You can see the result of calling in console:

As you can see, the function lb.get() was called 4 times instead of 5.

I think, i need something like a request queue.

You don't have handle for the error response method get. Maybe in this case, your response is disappear.

You don't need a request queue.

See example on jsfiddle.

angular.module('ExampleApp', [])
  .controller('ExampleOneController', function($scope, ServiceExample) {
    $scope.counter = 0;
    $scope.successCounter = 0;
    $scope.errorCounter = 0;
    $scope.$on('raise.event', function(event, value) {
      console.log('counter', $scope.counter);
      ServiceExample.get(value).then(function() {
        console.log('success response:', $scope.successCounter);
      }).catch(function() {
        console.log('error response:', $scope.errorCounter);
  .controller('ExampleTwoController', function($scope) {
  $scope.raiseValue = "www.google.com"
    $scope.raise = function(val) {
      $scope.$emit('raise.event', val);
  .service('ServiceExample', function($http) {
    return {
      get: function(url) {
        return $http({
          method: "GET",
          url: url
.errors {
  color: maroon
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="ExampleApp">
  <div ng-controller="ExampleOneController">
    <form name="ExampleForm" id="ExampleForm">
    <pre>counter : {{counter}}</pre>
