Why does my tablesorter keep caching my old rows?

I'm using tablesorter to sort a grid on one of my pages. I'm making an AJAX call every 10 seconds for updated stock information, and updating my grid accordingly. That much is working, but I can't get my sort options to cache properly. Rather, I seem to have cached the sorting, but when I do, tablesorter also caches my previous rows, and displays them along with the new, sorted set of rows. Example, my initial grid has 10 rows of data. I sort on the second column. After 10 seconds, a new set of 10 rows come in, but my initial 10 rows still show up, even though I've emptied them out. I've researched all over, and I can't seem to find the answer for this. If I don't sort at all, and I don't call the trigger for "sorton", I get my 10 rows as desired, but the rows aren't sorted of course. If I call that trigger for "sorton", my data gets sorted, but I get 10 new rows every time the function gets called (20 rows total, then 30 rows total, etc). Here is my code from inside my AJAX call: ``` if (myResult.Data.length > 0) { $.each(myResult.Data, function() { myRows += "<tr><td>" + this.column1 + "</td><td>" + this.column2 + "</td></tr>"; }); $("#myTBody").empty(); // $("#myTBody").append(myRows); //tried this first // $("#myTable").trigger("update"); // combined with this $("#myTBody").append(myRrows).trigger("update"); var sorting = $("#myTable")[0].config.sortList; $("#myTable").trigger("sorton", [sorting]); } ```
