jQuery buttonset change

Question

I'm new to jQuery and thought I would use its buttonset instead of some radio buttons on my application. Documentation here: http://jqueryui.com/demos/button/#radio

How do I add a handler to an event when the set of buttons changes value?

Here is a snippet of the code I tried:

$('input.tod_quant').change(function() {
    alert('TEST');
});

And then later on in the HTML:

<span id="tod_quant" class="buttonset">
        <input type="radio" id="tod_quant5" name="tod_quant" value="5" /><label for="tod_quant5">5-Minute</label>
        <input type="radio" id="tod_quant60" name="tod_quant" checked="checked" value="60" /><label for="tod_quant60">60-Minute</label>
        </span>

The "change" event never fires. Is there even a change event? How can I do this? Furthermore, is there any documentation with an example? http://jqueryui.com has plenty of examples, and not a single one that I can find shows any events firing. I suppose my ignorance of jQuery isn't exactly helping the situation.

Any help would be most appreciated. Thank you.

Ha! Problem solved. I've been hacking at this all day, and it was right in front of me.

I just needed to change how I was selecting the element to this:

$('#tod_quant')

Solution 2

There's no change event for buttons in jQuery-UI.

You should listen to change or click event of the underlying radio-buttons:

I had this problem, and I solved this as below: I created an event handler for labels:

$('.label-class').click(LabelClicked);
$('.input-class').change(InputChanged);
function LabelClicked() {
    var input = $('#' + $(this).attr('for'));
    if(input) 
        input.trigger('change'); 
    return true;
}
function InputChanged() {
    //do your work with this event
}

no other way! I tested several ways and finally decided to do this
