I'm mobile so I can't recheck your Fiddle now, but it creates a bit of a moving target if your "example" code isn't really to spec. There is likely a design re/decision that we can help you make if you can describe the wider UI/client-side goals of your app. Moo has more abstractions/macros than just call()/bind() type stuff (for example, the Form.Request class).
