Use a factory in AngularJS - ruby-on-rails

Question

When a button is clicked, I want to create a new User, and redirect the person to http://www.myapp.com/#/user/134.
The below code works, but am I using AngularJS factories correctly? It feels strange to have to define a 'createUser' function in my controller.
myApp.factory('User', ['$resource', function($resource) {
return $resource("/users/:id", { id: "#id" },
{
'create': { method: 'POST' },
'index': { method: 'GET', isArray: true },
'show': { method: 'GET', isArray: false },
'update': { method: 'PUT' },
'destroy': { method: 'DELETE' }
}
);
}]);
myApp.controller('splash', ['$scope', '$http', '$location', 'User', function($scope, $http, $location, User){
$scope.createUser = function(){
User.create(
{},
function(response){
$scope.user = response;
$location.path('/users/' + $scope.user.id);
},
function(){
console.log('error creating user');
});
}
}]);
Here is a view with a button for creating a new user:
<button ng-click="createUser()">Create User</button>
