[jQuery] sortStart and sortEnd triggers - tablesorter

[Soledad Zubiri]

Hello, I am here again and I explain you my problem:

 This table has the option to select the required row through a radio
button. But the problem is that if I sort the table (by any column) after
selecting some row, the selection goes off.
 I think that maybe I can use the sortStart and sortEnd triggers to
maintain the state of the radio buttons in the table after sorting, but I`m
 still having problems.

 $("#tarjetas").tablesorter({widgets: ['zebra']});

 <table id="tarjetas" class="tablesorter" align="center"  width="100%">
   <tr>
   <td>&nbsp;</td>
   <td><a href="#">Tarjeta</a></td>
   <td ><a href="#">Descripci&oacute;n</a></td>
  </tr>
  <tr>
   <td  id="CreditCardIndex" width="30">
    <input type="radio" id="CreditCardIndex" name="CreditCardIndex"
onclick="chequearRadio();"  >
   </td>
   <td ><wfs:wfwrite name="CreditCardBeanCollection"
 property="formatedNumber" scope="page"/></td>
   <td ><wfs:wfwrite name="CreditCardBeanCollection" property="description"
scope="page"/></td>
  </tr>
 </table>

function chequearRadio() {
  for (var i=0;i<document.formaSelectCard.elements.length;i++) {
  var e = document.formaSelectCard.elements[i];
  if ((e.type == objectType)&&(e.checked)){
   document.formaSelectCard.selectedIndex.value = e.value;
  }
 }
}


 Can anybody help me with this?
 Thanks a lot!

 Soledad.
