Is it possible to re-execute javascript in an UpdatePanel?

[Flis]

I have the following:\[code\]<asp:UpdatePanel ID="upd" runat="server"> <ContentTemplate> <script> alert("execute again"); </script> <asp:LinkButton ID="go" runat="server" Text="Exec JS" /> </ContentTemplate></asp:UpdatePanel>\[/code\]The first time the page renders the script is executed. If I click the button to cause a postback it doesn't execute again.Is there a way to make it execute the scripts again?
