just to test, try ajaxComplete()

something like :

$('#theList').ajaxComplete(function(){
   <!-- attach change event -->
});

  • Just a clarification for anyone reading this answer: ajaxComplete will work only when the inputs are added after an ajax call. It won't work if the items are added dinamically but not using ajax in the process of adding it.
  • According to the documentation, change does work with radio buttons. Also, can you clarify why you're using die() in an init function?
  • I mentioned it in my original answer, I put it there so that the elements don't stack the same event multiple times except just once. Change works, however I always use "click" for the radio buttons since it works across all browsers without issues.
  • Please note that this won't work for elements added dynamically to the DOM. That was the issue the OP initially had.
  • please use $(document).on('change', '#theList li input', function() {});
  • I was just pointing that out. I had posted an answer before covering that matter, just saying in case you wanted to edit yours.
  • thank for mentioning this I have updated my answer :)
