title: JQuery delegate not working for certain inputs
body: <p>I'm tring to use JQuery to automatically sum inputs in a table where rows are added dynamically. $().delegate and $().live do not seem to work if the selector contains an input with a name with [ ]. The same selector works with bind.</p>
  
  <p>Here is a sample code :</p>
  
  <pre><code>&lt;div id="area"&gt;
    &lt;input name="x[]"/&gt;
    &lt;input name="x[]"/&gt;
    &lt;input name="x[]"/&gt;
    &lt;input name="x[]"/&gt;
  &lt;/div&gt;
  
  $("#area").delegate("input[name='x\\[\\]']", 'change', function () {
    console.log($(this).val());
  });
  </code></pre>
  
  <p>Any suggestions on how to fix this ?</p>
