I try to append() a radio input to a table.After that I found the radio event can not trigge,

for example: I try to use to code:

$('input:radio').click(function() { alert('good'); });

This code could work when html page have the radio element, but after dynamically append radio element to the page, It seems the event could not work ! And I try to use click, focus, change, select event, but none of them working.
