Help, $http.get request returns undefined on first call?

I am currently working on a client with angularjs 1.5.8, and I have a service called AuthenticationService.

discovrApp.factory('AuthenticationService', function (
  $http,
  $rootScope,
  $localStorage,
  jwtHelper,
  apiURL){
  var service = {};

  var config = {headers:  {
      Authorization: '',
          'Content-Type': 'application/json'
      }
  };

  service.Login = Login;
  service.Logout = Logout;
  service.SignUp = SignUp;

  service.Profile = Profile;
  service.ChangePassword = ChangePassword;
  service.ResetPassword = ResetPassword;
  service.GetProfile = GetProfile;
  //service.SignUp = SignUp;
  //service.SignUp = SignUp;


  return service;

  function Login(username,password,callback) {
    $http.post(apiURL + 'api/rest/auth/login/', { username: username,   password: password })
      .success(function(response){
        //login successful if there's a token in the respose
        if(response.token){
          //decode token, to get the user id insert on payload
          var token = jwtHelper.decodeToken(response.token);
          var userProfile = 0;
          userProfile = GetProfile(token.user_id);
          console.log(userProfile);
          //store username and token in local storage to keep user logged in between paga refreshes
          $localStorage.currentUser = {id: token.user_id, username: username, token: response.token };
          //config.headers.Authorization = 'JWT ' + response.token;
          //add jwt token to auth header for all requests made by the $http services
         $http.defaults.headers.common.Authorization = 'JWT ' + response.token;
          //execuete callback with true to indicate successful login
          callback(true);
        }else{
          //execute callback with false to indicate failed login
          callback(false);
        }
      });
  }

  function Logout() {
    $http.post(apiURL + 'api/rest/auth/logout/')
      .success(function(response){
        //remove user from local storage and clear http auth header
        delete $localStorage.currentUser;
        localStorage.removeItem('user');
        config.headers.Authorization = '';
        $http.defaults.headers.common.Authorization = '';
      });

  }

  function SignUp(callback,username,password1,password2,email,more){
    $http.post(apiURL + 'api/rest/auth/registration/', { username: username, password1: password1, password2: password2, email: email})
      .success(function(response){
        //login successful if there's a token in the respose
        if(response.token){
         console.log(response.token);
         //store username and token in local storage to keep user logged in between paga refreshes
          $localStorage.currentUser = { username: username, token: response.token };
          //add jwt token to auth header for all requests made by the $http services
          $http.defaults.headers.common.Authorization = 'JWT ' + response.token;
          //execuete callback with true to indicate successful login
          callback(true);
        }else{
          //execute callback with false to indicate failed login
          callback(false);
        }
      });
  }

  function Profile(){
    $http.get(apiURL + 'api/user/' + $localStorage.currentUser.id + '/').
      then(function successCallback(response) {
          localStorage.setItem('user', JSON.stringify(response.data));
          console.log(response.data)
      }, function errorCallback(response) {
          console.log(response);
     });
  }

  function GetProfile(id){
    $http.get(apiURL + 'api/user/' + id + '/').
    then(function successCallback(response){
      $rootScope.userProfile = response.data.Kind;
      localStorage.setItem('profile', $rootScope.userProfile);
      //console.log(($rootScope.userProfile = response.data.Kind)); 
    });     
    return $rootScope.userProfile;
  }
});

I have the problem with the Profile() and GetProfile() functions, when I call them for the first time they always return or assign "undefined", and if I leave a console.log in the functions to print the result of the api, first it returns undefined, and if I call it again, it returns or assigns the value, the problem is the first time I always call it, it always returns undefined and the second time it doesn't, I would like to know if anyone has happened to it and knows the reason and how to fix this.

**NOTES: In the service that I create you will be able to notice several things, and that is that I have tried different ways such as saving the data returned by the get request in a local variable, and then printing this local variable, without a positive result at the first attempt. When refreshing the page, and trying again, it returns undefined at first and then returns it.

Thanks in advance, Regards.
