hitTest trigger event AFTER wheel has finished spinning?

1

I have a wheel that the user can spin by flicking it with a mouse (think wheel of fortune). It needs to trigger an event once the spinning has finished depending on what section of the wheel it has landed on. I can get it to trigger an event but it triggers every time the wheel passes the hitTest object, not just when it is done. I’ve attached a sample of it. All help is appreciated, as I am really pulling my hair out on this one.
