sequencing - configure, require(), initializing w/ onInit() and save() ...and bind()

Did you try this on desktop JavaScript? I just did with jsbin and it behaves exactly the same way in your first example.

I think your problem is that you're not using bind correctly. bind returns a bound function, but doesn't alter the one you pass as an argument.

So:

a.bind(b); // does nothing
a = a.bind(b); // does what you want
