Using jQuery, you can check whether the element exist.

    // Do code

I always do that check when I'm using DataTables or some other JS plugins. I first check if that table exists, then if yes, I initialize DT to that table. It always works for me.

By the way, the code above will only return 0 or 1 (true or false equivalents) so no need to do if($('#texttwo_'+rowid).length > 0)
Correct me if I'm wrong.
