I've been using jquery to trigger events on dynamically generated text fields using on, delegate and alike, just as described in this answer.  That works very well, but when I try to add another dynamically generated layer, I can't get the action to trigger.  So for example
Dynamically adding people to a list is fine
| People List
|
| 1) Name _______
|
|  ---------------------
| |Click to add a person|
|  ---------------------
|
If I want to dynamically add people to a list and trigger an alert each time the focus is on the text box the following works fine for that
$('div.people-list').delegate('input.name', 'focusin', function(){
  alert("textbox focusedin");
});
The Problem Comes when I have a list of lists. So say I wanted to have a dynamic list of multiple buses with a dynamic list of multiple passengers. Something like below.
| Bus List
|
|  1)  Bus ID_______
|   
|   | Passenger List
|   |
|   | 1) Name _______
|   |
|   |  ---------------------
|   | |Click to Add a Person|
|   |  ---------------------
|
|  ------------------
| |Click to Add a Bus|
|  ------------------
Under those circumstances, it seems that my above javascript using delegate is not sufficient.  What do I need to add to trigger events on this sort of nesting?
In the even that it matters (though I don't think it would), I'm using rails and the cocoon gem for the field dynamics.
