title: listening for table rows count change
body: <p>I was using the html table. My requirement is, i want to listen for the changes of rows count. Is there anyway to achieve this?</p>
  
  <p>Note: I don't have the adding/deleting a row functions here to achieve.</p>
  
  <p>Moreover that, i have tried this,</p>
  
  <pre><code>$("#myTable&gt;tbody&gt;tr").watch("length", function () {
      alert("row count changed..")
  });
  </code></pre>
  
  <p>But, the above code doesn't work for me. Could any of you know how to do this?</p>
  
  <p>Thanks in advance,</p>
  
  <p>-Raja.</p>
