Issue Implementing Expand Framework Solution to Suggeston S18977.

Hi Apostolis,
I have tried to implement the solution provided in https://www.devexpress.com/Support/Center/Question/Details/S18977 but without including Expand Module… i.e. taking code. I does not work for me.
I have taken below selected class/Enums from Expand source code.
EnumExtensions
FlagsEnumDifference<T>
public enum Keys
public enum Shortcut
public interface IModelOptionsWebShortcut
public interface IModelWebShortcut : IModelNode
public partial class WebShortcutsController
public sealed class KeyShortcut
public class KeysConverter
jwerty.jsIt is displaying option of Web Shortcut in model but after running application when I click Control+Alt+Shift+N it not responding, I have attached demo project. When I am debugging the application on Page Pre-Render below script get generated.
jwerty.key("F5", function(e) {RaiseXafCallback(globalCallbackControl, 'KeybShortCuts', 'Refresh', '', false);return false;}); jwerty.key("ctrl+Shift+Alt+N",function(e) {RaiseXafCallback(globalCallbackControl, 'KeybShortCuts', 'New','', false);return false;});
