title: How to catch onchange event on multiple textbox field
body: <p>HTML code:</p>
  
  <pre><code>&lt;input type="text" name="percentage[]" value="1"/&gt;
  &lt;input type="text" name="percentage[]" value="2"/&gt;
  &lt;input type="text" name="percentage[]" value="3"/&gt;
  </code></pre>
  
  <p>I want to be able to catch change event by using JQuery when any of the 'percentage' text fields changes and find sum of all these fields. So, if the value on the first field changes from 1 to 5, I want to be able to display "10".</p>
