How to make change event work for radiobutton for html added with replaceWith

I managed to get the change event firing for a radiobutton. However I now needed it to work for html where the radiobutton is added to the markup with replaceWith.

So it is added to my markup with:

$(this).replaceWith('<input type="radio" name="variety" value="null" id="myradio" />');

So, the code I have for catching the change event is:

$('#myradio').change(function () {

So does anyone know how I would make this work given the radio button is now added to the page after the initial page load?


You could use .on() (jQuery 1.7+) or .delegate() (jQuery 1.4.3+) to subscribe to the change event in order to account for dynamically added elements.

For example:

$('#myradio').live('change', handler);                // jQuery 1.3+

$(document).delegate('#myradio', 'change', handler);  // jQuery 1.4.3+

$(document).on('change', '#myradio', handler);        // jQuery 1.7+

It's also important to point out that it is not necessary to place this subscription inside a document.ready callback.

You could use the following:

$('body').on('change', '#myradio', function () {

If you know beforehand the element in which you'll be putting the radiobutton, you should change the 'body' selector to match that element for performance.


  • use jQuery on to a parent

    <div id="container">
        <!--replaceable elements-->
    //this will take effect on current and future children
  • or bind directly to the new element

    function func(){
    var newEl = $('<input type="radio" name="variety" value="null" id="myradiobutton" />');

i prefer the first one though, for performance and clean code.

You could create the radio button, add the change event, then replace this with the radio button.

var $radio = $('<input type="radio" name="variety" value="null" id="myradio" />');
$radio.change(function () {
