    AjaxEvent handler in VB does not seem to work

    I have the following in codebehind in VB:

            Dim btnSearch As New Coolite.Ext.Web.Button
        With btnSearch
            .Text = "Search"
            .AjaxEvents.Click.EventMask.MinDelay = 5000
            .AjaxEvents.Click.EventMask.ShowMask = True
            .AjaxEvents.Click.EventMask.Msg = "Performing search..."
            AddHandler .AjaxEvents.Click.Event, AddressOf btnSearch_Click
        End With

    Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As Coolite.Ext.Web.AjaxEventArgs)
        '-- do something
    End Sub
    It gives a runtime error when click on the button. It doesn't even make it to the btnSearch_Click routine. Is this a bug??
