Your callback function is just like any other function. It gets called
at a specific point, is passed some parameters, and the return value
then goes on to get saved to the database. If you don't run your code
from your callback function then you're just going to run it inside
another equally capable function. Your functions aren't bothered about
their supposed intent.
