jQuery .on('change', function() {} not triggering for dynamically created inputs

The problem is that I have some dynamically created sets of input tags and I also have a function that is meant to trigger any time an input value is changed.

$('input').on('change', function() {   // Does some stuff and logs the event to the console }); 

However the .on('change') is not triggering for any dynamically created inputs, only for items that were present when the page was loaded. Unfortunately this leaves me in a bit of a bind as .on is meant to be the replacement for .live() and .delegate() all of which are wrappers for .bind() :/

Has anyone else had this problem or know of a solution?

You should provide a selector to the on function:

$(document).on('change', 'input', function() {   // Does some stuff and logs the event to the console }); 

In that case, it will work as you expected. Also, it is better to specify some element instead of document.
