Why should anything fire? In your code sample, I don't see where you add an event handler to an invocation list of any event instance.
Nothing to fire, it looks like. :-)

You need to get an edit control of the cell, make sure it's a check box, and then add an handler to the invocation list of the event CheckedChanged.
