Angular - TypeError: XX is not a function

Maybe I'm missing some kind of property, but I'm follow this project and I'm getting this error in my controller.

TypeError: loginService.signin is not a function

This is my controller.js

angular.module('appcontrollers', []).controller('LoginController', ['$rootScope', '$scope', '$http', '$location', '$localStorage', 'loginService',  
        function ($rootScope, $scope, $http, loginService) {

        $scope.signin = function() {

            console.log("username: " + $scope.username);
            console.log("pass: " + $scope.password);

            var formData = {
                username: $scope.username,
                password: $scope.password
            };

            // ERROR IN THIS LINE
            loginService.signin(formData, function(res) {
                console.log("asdf");
                if (res.type == false) {
                    console.log(res.data);
                } else {
                    $localStorage.token = res.data.token;
                    console.log("Window location /");
                }
            }, function() {
                $rootScope.error = "Error en el logueo del usuario";
            });

            // Setting Token:
            $scope.token = $localStorage.token;
        }

    }])

This is my service.js

'use strict';

angular.module('app-services', [])
.factory('loginService', ['$http', '$localStorage', function ($http, $localStorage) {
    console.log('services - loginService');

    var baseUrl = "http://angular-restful-auth.herokuapp.com";

    function changeUser(user) {
        console.log('1');
        angular.extend(currentUser, user);
    }

    function urlBase64Decode(str) {
        console.log('2');
        var output = str.replace('-', '+').replace('_', '/');
        switch (output.length % 4) {
            case 0:
                break;
            case 2:
                output += '==';
                break;
            case 3:
                output += '=';
                break;
            default:
                throw 'Illegal base64url string!';
        }
        return window.atob(output);
    }

    function getUserFromToken() {
        console.log('3');
        var token = $localStorage.token;
        var user = {};
        if (typeof token !== 'undefined') {
            var encoded = token.split('.')[1];
            user = JSON.parse(urlBase64Decode(encoded));
        }
        return user;
    }

    // Set user token.
    var currentUser = getUserFromToken();

    return {
        save: function(data, success, error) {
            $http.post(baseUrl + '/signin', data).success(success).error(error)
        },
        signin: function(data, success, error) {
            $http.post(baseUrl + '/authenticate', data).success(success).error(error)
        },
        me: function(success, error) {
            $http.get(baseUrl + '/me').success(success).error(error)
        },
        logout: function(success) {
            changeUser({});
            delete $localStorage.token;
            success();
        }
    };
}

]);

My application works until the user press the submit button called signin() from a form. Then I got this two lines in my console with the correct data

>> username: somename
>> pass: somepassword

And after that the error shows up. Can anyone help me in order to pass this signin() function?

You are messing with Dependency injection array, that should follow correct order of dependency when you are using it in a function.

Code

angular.module('appcontrollers', []).controller('LoginController', ['$rootScope', '$scope', '$http', '$location', '$localStorage', 'loginService',  
        function ($rootScope, $scope, $http, $location, $localStorage, loginService) {
