As you said it's obvious, hopelessly I can't go that way as I have to
change the callback on the button only when what I'm doing in the original
callback succeeds.

What I want to do is :

In my function NewCustomer, I have a  button which alls the
\&SaveCustomer function. If this function successfully save the
data, I rename the button to 'Create a new customer' and connect it to the
NewCustomer function.

It works, but my only problem is that the first connected signal is still
emited, so it tries to save the customer's data again and then calls the
NewCustomer function.
