[jQuery] [Ajax request]Can a dialog not show an alert message?

[delphilynx]

Hi everyone,

I have an event that fires up a dialog, this all is working:
1) dialog have two buttons
     - Save button
     - Close button
2) when hitting the save button, it creates an Ajax Request, and on
the succes event it must fire an alert with the message that comes
back from the backend script.
3) in Firebug is the message back shown, but not in the Alert, how to
deal with this?

Thanks in advance
