How to uncheck (unclick) a checked radio button widget in jQuery Mobile?

Question

I have a group of radio buttons in a jQuery Mobile application. I would like to "uncheck" a checked radio button when I click on it again, so none of the buttons in the group are highlighted and the "serialize" function called on the form doesn't return any value for that radio group. I can do that for desktops with such code:

$('form').on('click', 'div:has(>.ui-radio-on)', function(event) {
  event.stopPropagation();
  $(this).find('input').prop('checked',false).checkboxradio('refresh');
})

You can test it at http://jsfiddle.net/xqqauoq3/.

Unfortunately it doesn't work on Firefox for Android nor Chrome for Android.

How to implement that functionality so it works on both mobile and desktop?
