First, terminology disputes are pointless.

No, I would never call f a method of Dialog. I might call it a method of
dialog, though.

A method is simply a callable attribute:

   Procedures in object-oriented programming are known as methods

(Now, in CLOS, GOOPS etc, methods are not attributes at all, but that's
another story.)
