RadButton's onClientClicked event can't close current RadWindow

[Ray]

The Live Examples：window/examples/clientsideevents
(My version is  AJAX Q3 2013 released 10/15/2013)
in "Dialog.aspx",I just replace asp Button with RadButton, the OnClientClicked does not work.
Here is "Dialog.aspx" code snippet whitch i added a  RadButton :

<table style="text-align: center; width: 250px;">
    <tr>
        <td>
            To provide an argument, fill in the value and click on "Close with argument" button
            below:<br />
            <br />
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
            <br />
            <asp:Button ID="Button1" runat="server" Text="Close RadWindow" OnClientClick="Close();return false;" /><br />
            <br />
            <asp:Button ID="Button2" runat="server" Text="Close with argument" OnClientClick="CloseWithArg();return false;"/>
            <br />
            RadButton1 is added by myself,but the OnClientClicked event does not work.
            <telerik:RadButton ID="RadButton1" runat="server" Text="RadButton" OnClientClicked="Close();return false;"></telerik:RadButton>
        </td>
    </tr>
</table>

OK,the problem has solved.i mad a mistake on RadButton's onClientClicked event. It's diffent from asp Button's onClientClick.
