Does the formatter callback work?  I can't get it to do anything useful, using a lambda _expression_ stuffed into a variable.  How does the widget calll the desired function?

Hmm, just tried this and it worked:

lambda x: "Value = {0} (put units here)".format(perform_function_on(x))

So the _expression_ returns a string.
