Using datepicker

Using datepicker

Hi,
 
I am just picking up JQuery and started with the DatePicker control.  I have added a datepicker to my .NET page and it works fine, but is missing some of the cool functionality of the example from the JQuery site.   In this example http://jqueryui.com/demos/datepicker/, when you change the date within the textbox, the date highlighted on the calendar also changes to reflect this.  But when I use the code in the demo from the download, this does not happen.  Can anybody help?  Here is my code :
 

<%

@ Page Title ="" Language ="C#" MasterPageFile ="~/Views/Shared/Site.Master" Inherits ="System.Web.Mvc.ViewPage" %>

<

asp : Content ID ="Content1" ContentPlaceHolderID ="TitleContent" runat ="server">

Client

</

asp : Content >

<

asp : Content ID ="Content2" ContentPlaceHolderID ="MainContent" runat ="server">

< h2 > Client </ h2 >

<%

using (Html.BeginForm()) { %>

< div class ="demo">

< p > Date: < input type ="text" id ="datepicker" /></ p >

</ div >

<% } %>

</

asp : Content >

<

asp : Content ID ="Content3" ContentPlaceHolderID ="ScriptContent" runat ="server">

< script type ="text/javascript" src ="/scripts/jquery-1.3.2.min.js"></ script >

< script type ="text/javascript" src ="/scripts/ui.core.js"></ script >

< script type ="text/javascript" src ="/scripts/ui.datepicker.js"></ script >

< script type ="text/javascript">

$(

function () {

$(

"#datepicker" ).datepicker();

});

</ script >

</
