Problem on rasing DirectEvent on Desktop control.

Hi Ext

At first thanks so much about Ext components. I'm appreciated.
I'm adding a dynamic module into my desktop control but I have problem on raising DirecEvents. My code is

Code:

---

    [DirectMethod(ShowMask = true)]
    public void AddAnotherModule()
    {
        Desktop.GetInstance().RemoveModule("add1-module");

        var win = new Window
        {
            Title = "Dynamic Window",
            Width = 300,
            Height = 300,
            DefaultRenderTo = Ext.Net.DefaultRenderTo.Form,
            Icon = Icon.ApplicationAdd
        };

        DesktopModule m = new DesktopModule
        {
            ModuleID = "dyn-mod",
            Shortcut = new DesktopShortcut
            {
                Name = "Dynamic Module"
            },

            Launcher = new Ext.Net.MenuItem
            {
                Text = "Dynamic module"
            },

            Window =
            {
                win
            },

            AutoRun = true
        };

        var btn = new Ext.Net.Button
        {
            Text = @"DynamiC Button"
        };
   
        btn.DirectEvents.Click.Event += OnClick;
        m.Window[0].Items.Add(btn);

        Desktop1.AddModule(m);
    }

    protected void OnClick(object sender, DirectEventArgs e)
    {
        X.Msg.Alert("OnClick", "DirectEventArgs");
    }

Why Click event of DirectEvents raising this error and it can not find my Button control?

Error message is "The control with ID 'button-1066' not found".
