asp.net - javascript inside Usercontrol inside updatepanel is undefined -


i'm facing little problem here :

i have aspx page contains update panel has place holder (in content template) containing different usercontrols show/hide depending on conditions.

one of them has long script inside initializing function has controls retrieved server tags ( <% #myctrl.clientid%>) values etc.. , thing when call function once updatepanel finishes updating, says it's undefined..

as if usercontrol script wasn't seen @ all,

here aspx page "initializefees" function call when update finished: 

 <asp:scriptmanager id="scriptmanager1" runat="server" enablepartialrendering="true"             enablepagemethods="true"> <asp:updatepanel runat="server">         <contenttemplate>             <script type="text/javascript">      sys.webforms.pagerequestmanager.getinstance().add_endrequest(initializefees);              </script>         <div class="registration_progresscontent">             <uc3:ctrl_registrationprogress id="ctrl_registrationprogress1" runat="server" onselectedindexchanged="changestep" />         </div>     </div>     <div class="registration_stepcontent">         <asp:placeholder runat="server">             <uc1:ctrl_registrationgeneral id="ctrl_registrationgeneral1" runat="server" visible="false" />             <uc4:ctrl_registrationfee id="ctrl_registrationfee1" runat="server" visible="false" />

and here "uc4:ctrl_registrationfee" html code :

<%@ control language="vb" autoeventwireup="false" codebehind="ctrl_registrationfee.ascx.vb"     inherits="mdsinscription.ctrl_registrationfee" %> <script type="text/javascript">      //validateurs     var valteam;     var valemail;     var imgname;      function initializefees() {         valteam = $('#valcreateteamname');         valemail = $('#valcreateemail');          $("#accordion").accordion({         //activate: function (event, ui) {         //    //                validateselection();         //}     });

with code behind (vb.net.....#joy..) : 

private sub page_prerender(byval sender object, byval e system.eventargs) handles me.prerender      scriptmanager.registerclientscriptblock(me, page.gettype(), "init", "initializefees();", true)  end sub

this code got after searching more hour, , following error : 

uncaught referenceerror: initializefees not defined

if feel can help, thanx !

problem solved following script, put outside update panel : 

    function pageload() {         $(".datepicker").datepicker({             changemonth: true,             changeyear: true,             mindate: "-100y",             maxdate: "-15y",             dateformat: "dd/mm/yy",             yearrange: "1913:2300"         });         //more code executed on each postback update panel ...         }
