title: input (checkbox) not working in IE8 when configured with :checked
body: <p>For my checkbox (following), I used the JQuery condition (:checked) to check if the checkbox is clicked on. It works fine in all the browsers but just doesn't work in IE8. Any idea or assistance?</p>
  
  <pre><code>&lt;input type="checkbox" id="chbx" name="samechbx" onchange="checkbox_changed(this)" /&gt;
  </code></pre>
  
  <h2>JS</h2>
  
  <pre><code>function checkbox_changed(el) {
  
          if ($('#chbx').is(":checked")) {
              //if checked, move in.
          }
  }
  </code></pre>
