How to uncheck checked radio button

Question

The thing is this solution work only in firefox

$(':radio').on("change", function(event) {
  $(this).prop('checked', true);
});

$(':radio').on("click", function(event) {
  $(this).prop('checked', false);
});

In chrome, it wont allow you to select anything http://jsfiddle.net/wuAWn/

Ofc, i could use variable and write something like

var val = -1;
$(':radio').on("click", function() {
  if($(this).val() == val) {
    $(this).prop('checked', false);
    val = -1;
  }
  else val = $(this).val();
});

But i will have few radio button groups on my page and html content is loaded through ajax, so i would like to wrtite 1 function for all of them, instead of defining variables for every one radio button group and write same function for every radio button group.

Edit: thanks for your help with checkboxes, but for checkboxes to act as a radio button group, you need to write adittional javascrip that will uncheck all other checkboxes with same name onclick, i have already radio button css and its easier for me just to add class like look-like-checkbox and make it look like checkbox, i use uniform library for custom look, anyway here is my weird solution http://jsfiddle.net/wuAWn/9/

This simple script allows you to uncheck an already checked radio button. Works on all javascript enabled browsers.

var allRadios = document.getElementsByName('re');
var booRadio;
var x = 0;
for(x = 0; x < allRadios.length; x++){
  allRadios[x].onclick = function() {
    if(booRadio == this){
      this.checked = false;
      booRadio = null;
    } else {
      booRadio = this;
    }
  };
}

<input type='radio' class='radio-button' name='re'>
<input type='radio' class='radio-button' name='re'>
<input type='radio' class='radio-button' name='re'>
