jquery tablesorter + ajax div content update problem

Question

I'm having trouble with my tablesorter and ajax div content update. Once the ajax is reloaded all the tablesorter functionalities are lost. I've tried livequery but it doesn't seem to work beyond first listing of the table.

<script type="text/javascript">
    $(document).ready(function(){
        $(".tabs > ul").tabs();
        $("#sortabletable").tablesorter({
            headers: {
                4: { sorter: false },
                5: { sorter: false }
            },
            widgets:['zebra'],
            sortlist:[[0]]
        });
    });
    $("#sortabletable").livequery(function(){
       $(this).tablesorter({
            headers: {
                4: { sorter: false },
                5: { sorter: false }
            },
            widgets:['zebra'],
            sortlist:[[0]]                          
       });
    });

</script>


// The AJAX function...
function AJAX(){
   try{
       xmlHttp=new XMLHttpRequest(); // Firefox, Opera 8.0+, Safari
       return xmlHttp;
   }
   catch (e){
       try{
           xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); // Internet Explorer
           return xmlHttp;
       }
       catch (e){
           try{
               xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
               return xmlHttp;
           }
           catch (e){
               alert("Your browser does not support AJAX.");
               return false;
           }
       }
   }
}

// Timestamp for preventing IE caching the GET request (common function)
function fetch_unix_timestamp(){
   return parseInt(new Date().getTime().toString().substring(0, 10))
}

   // Create xmlHttp

     // No cache
   var timestamp = fetch_unix_timestamp();
   var nocacheurl = url+"?t="+timestamp;

   // The code...

           document.getElementById(divid).innerHTML=xmlHttp_one.responseText;
           setTimeout('events_listings()',seconds*1000);
       }
   }
   xmlHttp_one.open("GET",nocacheurl,true);
   xmlHttp_one.send(null);

// Start the refreshing process

Instead of calling .tablesorter() again, you can trigger an update instead, without any of the overhead of calling .tablesorter():

("#table").trigger("update");

I've used this successfully in my own project. You can make the trigger() call in your :success handler.
