"insert_user_form" is local to "insertUser" so validate won't be able
to "see" it. If you really want to define the form inside the
controller method you should declare "insert_user_form" as being
global, however, you could... errr, wil run into thread-safety issues
if you do that.
Really, forms (and widgets in general) were designed to be declared
just once outside any controller method and be reused in any controller
that needs them... they're stateless (hence thread-safe) so there's no
risk in doing that (unless you change a mutable attribute, which you
shouldn't).
Sorry for being so repetitive but... what exactly frightens you about
instantiating the form outside your controller? ;) From the use-case
you're showing in your code there's nothing preventing you from doing
it that way (unless I'm missing something).
