title: How to check/uncheck radio button on click?
body: <p>I want to be able to uncheck a radio button by clicking on it.</p>
  
  <p>So, if a radio button is unchecked, I want to check it, if it is checked, I want to uncheck it.</p>
  
  <p>This does not work:</p>
  
  <pre><code>$('input[type=radio]:checked').click(function(){
      $(this).attr('checked', false);
  });
  </code></pre>
  
  <p>I am not able to check a radio button now.</p>
