Javascriptでダイアログボックスを閉じた後にDatatableを自動的に更新する方法

ここに2つのJSファイルがあります。1つは親ページのメインJSファイルで、これにはajax呼び出しでデータが取り込まれるDatatableが含まれています。もう1つは、必要な値をデータベースに更新する関数が定義されている更新機能専用です。その更新はダイアログボックスで行われます。更新が成功すると、製品が正常に更新されたことを示す甘いアラートが表示されます。したがって、更新された値はすぐに親ページのデータテーブルに反映されるはずです。現在、古い値は、ページを手動で更新するまで表示されています。以下は両方のJSファイルです。そして、私はJavascriptとJqueryの初心者です。だから助けてください
