RadDatePicker SelectedDateChanged issue

I have RadDatePicker control with SelectedDateChanged event. When I change the Date the event fires with Confirm window. When I click on 'Cancel' button RadDatePicker1_SelectedDateChanged invokes again and it displays Confirm window twice. When I click on 'OK' button it works fine. What could be the problem? Thanks for any suggestions. 

  <telerik:RadDatePicker ID="RadDatePicker1" runat="server" AutoPostBack="true" OnSelectedDateChanged="RadDatePicker1_SelectedDateChanged" >
                         </telerik:RadDatePicker>


protected void RadDatePicker1_SelectedDateChanged(object sender, EventArgs e)
{
string radalertscript = "<script language='javascript'>function f(){ radconfirm('Are you sure?', confirmChange, 400, 100) ; Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
                     Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert33", radalertscript);
 }

Here is Javascript function

function confirmChange(args) {
    if (args) {
        __doPostBack("<%= hiddenButton1.UniqueID %>", "");
    }

It seems like an unnessary postback if you're just using it to render some javascript.

Could you do your confirm dialog on the client side?

http://www.telerik.com/help/aspnet-ajax/calendar-on-date-selecting.html

<script type="text/javascript">
function ConfirmChange(sender, eventArgs) {
    var date = eventArgs.get_renderDay().get_date();
    var dfi = sender.DateTimeFormatInfo;
    var formattedDate = dfi.FormatDate(date, dfi.ShortDatePattern);
    eventArgs.set_cancel(!confirm("Are you sure you want to " +
    (eventArgs.get_isSelecting() ? "select " : "unselect ") +
    formattedDate + "?"));
}
</script>

<telerik:RadCalendar ID="RadCalendar1" runat="server">
    <ClientEvents OnDateSelecting="ConfirmChange" />
</telerik:RadCalendar>
