Move from .bind() to .on()

In jQuery 2.0 `bind()` has been moved into a separate event-alias module and when using a custom jQuery build without it, jasmine-jquery breaks.

`bind()` has been deprecated [and calls `.on()` anyway](https://github.com/jquery/jquery/blob/master/src/event-alias.js#L18).
