The Problem witch Chosen Jquery and Postback in .net asp

Question

i am a problema in use Jquery Chosen in ASP.NET. The item performs a postback and has class="chosen-select". when performing the postback you lose the chosen-select. I have tried to add this script but it doesn't work:

$(document).ready(function () {Sys.WebForms.PageRequestManager.getInstance().add_endRequest(PageLoaded)}); function PageLoaded(sender, args) {$("#MainContent_ddlTabla").chosen();}
