Carousel - How to get overscroll event ?

In my application I have a need to know when a user reaches the end of a carousel or swipes back to the beginning. So if the user tries to scroll past what is there I can hook in to an event.

What's the best way to do this?

It doesn't like an event is fired in this case. Am I wrong?

Thank you.
