Regarding the document: http://backbonejs.org/#Model-save. I sent a 201 (or 202, 203) status respond code from server, however, error handler didn't get fired.
The non-200 status code in the docs refers to a status code that isn't a 200-level code. 2xx's are generally considered success codes, you'd want a 4xx or 5xx to trigger the error.
