Problem customizing ChangePassword control

[Jeff]

hi

I've added the markup below in the ChangePasswordTemplate, I thought that
when I hit the ImageButton the password would change, but nothing happpens.
Even RequiredFieldValidators isn't executed. I set CommandName to Submit, I
thought that should be correct (as PasswordRecovery uses Submit)?

<asp:ImageButton ID="ChangePassword" CommandName="Submit"
ImageUrl="~/Images/Go.gif" runat="server" />

any suggestions?
