Yes, #displayString is dynamic and changes as a result of #doSomething.
I stumbled upon #onComplete: as well, but could not figure out how to use it...

This whole area is a bit special: when you see solutions (or presentations about this) it all looks beautiful and elegant, and you think you understand it, but when you have to change it you get so easily stuck, frustrating.

I thought I'd have to use (the deprecated) onComplete: block with the Ajax object just to make sure the ajax callback is finished before I update the input field. So using your code and my idea it would look more like this:
