Onclick does not fire when i close a Radwindow with OnClientClick

[Ronan BARRANGER]

With this code, i try to Close a Window (the way i'm doing it works) but i have also an Onclick event which is ignored!

<script type="text/javascript">


             function GetRadWindow() {
                 var oWindow = null;
                 if (window.radWindow) oWindow = window.radWindow;
                 else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
                 return oWindow;
             }

             function CloseDialog() {
                 GetRadWindow().close();

             }

</script>

ASPX page:

           

<asp:Button ID="Button1" runat="server" Text="Soumettre ce ticket"
               onclick="Button1_Click"  OnClientClick="CloseDialog()"/>

My application never enters Button1_click event, can anyone help me to find out why ?
thanks in advance



EDIT: HTML GENERATED FOR THE BUTTON

<input type="submit" id="Button1" onclick="CloseDialog();" value="Soumettre ce ticket" name="Button1"/>

Solution :

<asp:Button ID="Button1" runat="server" Text="Soumettre ce ticket"
            onclick="Button1_Click"  OnClientClick="CloseDialog();"
            UseSubmitBehavior="false"/>
