jquery - jQueryデータテーブルがデータを更新しない

Question

サーバー側を使用してデータテーブルやその他の作業を埋めることができますが、要素をクリックした後にデータを更新することはできません。データreload_tableテーブルのクリアは正しく機能しますが、描画は機能しません。

Jクエリ:

$('#reload_table').live('click',function(){
   oTable_topics.fnReloadAjax(oTable_topics.fnSettings());
   oTable_topics.fnClearTable();
   oTable_topics.fnDraw();
    $.ajax({
       url: "server_processing.php",
       success: function() {
           // if it worked, ask datatable to redraw the table with the new data
           $("#showTopics").dataTable().fnDraw();
           // if this js function does anything useful (like deleting the row), then call it:
           Success();
       },
       error: function() {
           // display any error (like server couldn't be reached...), or at least try to log it
       }
    });
});
oTable_topics =$('#showTopics').dataTable({
