It’s not easy to use the delegate method, I don’t know why
$(selector).delegate(childSelector, 'change', function () {}

$(selector).on(event,subselector,function) Dynamically generated DOM event binding uses on
For jquery, it is usually bound with on.

The event will be triggered when the text box loses focus
