Hey guys I got it now,
$('.actualResults').remove();
$.each(smg, function(i, item) {
$('#ResultTable').append( '<tr><td>' + smg[i].Title + '</td><td>' + smg[i].EntryDate + '</td>\n\
<td>' + smg[i].id + '</td><td>' + smg[i].GenreName+ '</td></tr>' );
});
I use the remove function from the jquery and then render the new data with loop.
Thanks,
