Several oddities in the code you posted (e.g. you defined foo() but
instead call set_foo(); the `handle` variable comes out of nowhere)
suggest that it isn't your actual code; this greatly hinders us in
assisting you. Please post your /actual/ code verbatim (or as much of
it as you can with as few modifications as you can).
Also, avoid using "plz" in the future; it's gotten a reputation for
being associated with undesirable folk.
Cheers,
