jQuery and EmptyMessage attribute

[keymmachine]

Hello,

I'm trying to fill a RadInput that has an EmptyMessage with jquery but the field keeps the EmptyMessage formatting (gray)(see attachement). Is there a way to do this?

Input code

<asp:CheckBox ID="Copy" ClientIDMode="Static" runat="server" Text="Copy"  />
<telerik:RadTextBox ID="PHText" ClientIdMode="Static" EmptyMessage="optional" runat="server" MaxLength="10" />

JQuery code

$(function () {
        $('#Copy').click(function () {
            if ($(this).is(':checked')) {
                $telerik.$('#PHText_text').val('hello world');
            } else {
                $telerik.$('#PHText_text').val('');
            }
        });
    });

I figured this out.  I needed to use the set_value client side functions.
