No, you just have to observe from higher up. If you use
document.on('mouseover'... it will work no matter when or where you insert the
elements:

I'm not using an Ajax call here to create my new tables, but I am generating a
completely new object after the page load, and that object has no observers
defined on it. There's just a single observer at the document level, and it
listens to all mouseover and mouseout events but only acts when they happen
over a tr.
