Oh, and to answer "how do I trigger the error function?" You don't. The error callback is triggered automatically if the script times out, or a 404 status is returned, or your response data does not match your dataType, etc. Your focus is to get the user to not get to this 'error' callback, but it's more of a catch for uncontrollable failures (eg. network issues).
