My understanding is that Drupal.behaviours is just like .ready.  I don't 
understand your distinction between ajax and js, the J in ajax stands 
for javascript.  But at any rate, if you're doing something on an 
element that doesn't exist yet, then that's what .live is for.  Just put 
that in your js that is in your page on the element you're expecting.  
All .live really does is use event bubbling and event delegation to 
capture the event on a containing element.
