[jQuery] Call Function From AJAX Loaded Page

[Dave]

I am trying to call a function from this link ( <div
id="twitter_display"><div class="content">
Alright! New office chair!<br><a class="twitter" id="1">[next]</a></
div></div> )   I want this to activate on the click() of
a.twitter....................................................   but $
("a.twitter").click(function() {...     is not calling the function.
What do I need to replace "a.twitter" with to get this function to
call?  Thanks
