Nice man, good write up! Good job on keeping the binding definition (myBindingDefinition) out of the viewModel. I'd be interested to see a larger scale example of something with methods etc.

Okay.. I gave it a computed and css switching...
I got busted on this in the computed for longer than I wanted to. All good now though.
