Javascript code to detect any page changes? (maybe via AJAX)

I'm new to writing Javascript, and here's what I'm doing/trying to do.

When a page loads (window.onload) my Javascript code goes through all the forms in a page and attaches a certain onchange method to them. This works fine for most websites on the internet, except when a page dynamically updates to load more forms on the page. How do I detect such an event and re-run my function?

For example:

The Facebook Newsfeed has a bunch of forms associated with all the different statuses/links posted. My code goes through them and attaches the listener. But if go you all the way down the page automatically updates to reveal more statuses/links/etc. (or you click the "Older Posts" link) - but now my javascript code has not run globally again.

Anyway I can do that?

EDIT: I am writing a browser extension.
