Ok, I understand that. Thanks for the explanation. So it almost sounds
like I need to either have the events external to the tags or else I
need some code to evaluate the javascript in the tags (I found a pure
javascript example). But where would I put that code? In my main
page or inside the Ajax rendered view? Hmmm... maybe it doesn't
matter.
I think from my experiments I determined that code inside the <script>
tags was getting evaluated. But why isn't the $javascript->link
('filename') tag getting loaded I wonder?
