... which is quite normal, since you actually didn't define any binding.
What you did is:
- *Call* self.table.tk.call(self.table._w,'yview','scroll',-5,'units'),
which did the scroll;
- Pass the *result* of this call (which is probably None or the empty
string) as the second parameter of self.table.bind.
So no binding was defined.
One solution is to define the binding via a lambda, like this (untested):
self.table.bind("<Button-4>", lambda e, t=self.table: t.tk.call(t._w,
'yview', 'scroll', -5, 'units'))
