Your code string is missing a "\n" at its end.

BTW, what are you trying to achieve? It doesn't look like
the right path, I guess. Where do you want to put "my_function",
shall that become a new method for your instance?
Will not work, although there are ways to do this.

But before, I suggest to play more with classes and instances
in the way they are designed for, then you might be able to
avoid tricks like generating code.
