jQuery $("#radioButton").change(...) not firing during de-selection

Question

Looks like the change() function is only called when you check a radio button, not when you uncheck it. The solution I used is to bind the change event to every radio button:

$("#r1, #r2, #r3").change(function () {

Or you could give all the radio buttons the same name:

$("input[name=someRadioGroup]:radio").change(function () {

Here's a working jsfiddle example (updated from Chris Porter's comment.)

Per @Ray's comment, you should avoid using names with . in them. Those names work in jQuery 1.7.2 but not in other versions (jsfiddle example.).

<input id='r1' type='radio' class='rg' name="asdf"/>
<input id='r2' type='radio' class='rg' name="asdf"/>
<input id='r3' type='radio' class='rg' name="asdf"/>
<input id='r4' type='radio' class='rg' name="asdf"/><br/>
<input type='text' id='r1edit'/>                  

jquery part

$(".rg").change(function () {

if ($("#r1").attr("checked")) {
            $('#r1edit:input').removeAttr('disabled');
        }
        else {
            $('#r1edit:input').attr('disabled', 'disabled');
        }
                    });

here is the DEMO

You can bind to all of the radio buttons at once by name:

$('input[name=someRadioGroup]:radio').change(...);

This normally works for me:

if ($("#r1").is(":checked")) {}

My problem was similar and this worked for me:

$('body').on('change', '.radioClassNameHere', function() { ...
