Web Forms :: Can't Get Button Click EventHandler To Fire

I'm adding a Button to a TableCell dymanically in code-behind and cant get an event handler to work.

Here's some code...

...
TableCell tc = some TableCell....
Button b = new
Button();
b.Text = "Go";
b.Click += new
EventHandler(OnSequenceChanged);
...
protected void OnSequenceChanged(object Sender,
EventArgs Args)
{
}

I set a break at OnSequenceChanged, but it doesnt hit when I click the button. It posts back - Page-Load gets called - but its event handler doesnt get called.
