How to get the date displayed on the calendar in Hebrew with a client of the MSFT AJAX library (Sys namespace)?

I want to show the date with the he-IL culture and the Jewish calendar, but I have not had any success. I get the following:

Expected: יום שלישי ט "ז אייר תשע" ב

Actual: יום שלישי 08 שבט 2012

Only one part of the date is correctly calculated, any ideas why this is happening? Here is one example of using C # (it displays the date correctly) and the other with Javascript (it does not display the date correctly):

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent" >
<script type="text/javascript">
    function foo() {
        var d = new Date();
        var p = document.getElementById("txtHebrewDateJS");
        p.value = d.localeFormat(Sys.CultureInfo.CurrentCulture.dateTimeFormat.LongDatePattern);
    }
</script>
<asp:Label runat="server" Text="Hebrew calendar, culture he-IL, using code behind" />
<asp:TextBox runat="server" ID="txtHebrewDate" />
<br />
<asp:Label ID="Label1" runat="server" Text="Hebrew calendar, culture he-IL, using asp net ajax" />
<asp:TextBox runat="server" ClientIDMode="Static" ID="txtHebrewDateJS"  />
<br />
<asp:Button runat="server" Text="load hebrew date" onclientclick="foo();" />

Code behind:

using System;
using System.Globalization;
using System.Threading;

public partial class _Default : System.Web.UI.Page {
    protected void Page_Load(object sender, EventArgs e) {
        txtHebrewDate.Text = DateTime.Now.ToString(Thread.CurrentThread.CurrentCulture.DateTimeFormat.LongDatePattern);
    }

    protected override void InitializeCulture() { 
        var c = new System.Globalization.CultureInfo("he-IL"); 
        c.DateTimeFormat.Calendar = new HebrewCalendar(); 
        Thread.CurrentThread.CurrentCulture = c; 
        Thread.CurrentThread.CurrentUICulture = c; 
        base.InitializeCulture(); 
    }
}
