Arghh... I was beaten to an answer! :) Slow typing...
Yeah, with bindings you will get a two-way connection. If you change your
property's value programmatically, the stepper will update also.
Instead of target-action you could set up an iboutleted property, connect
stepper to it and observe that property for changes. This may be a more
cumbersome approach in this case though.
