Binding a function to ajax:success as morbaq suggested worked for me.

However, I think if there is more than one ajax behavior associated with the element, the function will run for each of them.

In case you also want to add listener for ajax send use following code 

$(document).ready(function() {
  $('#topnav-buildings').bind('ajax:beforeSend', function() {
    blockDiv('#topnav-buildings');
  });
});

I spent an hour to find these t2 things

  1. we have to put it inside document.ready
  2. S is in caps when you write ajax:beforeSend
  3. Dont use ajaxSend instead of ajax:beforeSend .... beacause it adds global handler for all ajax events

I'm having the same problem, and this post helped me figure it out. Basically you need to attach a listener to the element that reacts on rails' callback events. For example:

<%= link_to 'Delete', post, 
  :confirm => 'Are you sure?', 
  :method => :delete, 
  :remote=>true, 
  :id=>'delete' %>

In a separate js file (to make it unobtrusive), with jQuery:

$('#delete').bind('ajax:success', function() {
  // do something
});
