[JW Lua] Button press callback

"mybutton" is defined before the function, with file scope.

Jari,
Thanks for the info.

I usually place all my functions at the top of the file, which necessitates
declaring variables later on as global.  I can see the value of putting
functions later in the middle of the code, but it just seems odd to me.  If
I place the function at the bottom, then no matter if the variable is global
or local, the button press does nothing.  Why?

Charles
