Event not fire

Hey,

I created button dynamicaly and added handler to it, but for some reason, event do not fire, then I press it.

What can be wrong?

VB Code:

Protected WithEvents LeftPane As System.Web.UI.HtmlControls.HtmlTableCell
 
 Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            If Page.IsPostBack = False Then
 
 Dim myButton As New Button
                    myButton.Text = "Save"
                    myButton.ID = "SubmitButton"
                    AddHandler myButton.Click, AddressOf Me.Submitas
 
LeftPane.Controls.Add(myButton)
 
 
            End If
 
End Sub
 
        Private Sub Submitas(ByVal sender As System.Object, ByVal e As System.EventArgs)
 
            Response.Write("Click")
        End Sub

After PostBack is the button still on the page? And I think if you declare a null button outside of the Load event it may help, but in truth that shouldn't mater.
