R help - Nov 2016 - [tcltk] tktable: bindings doesn't triggers the ValidationCommand and Command

Dears,

I'm trying to create an Data Editor like Rgui.exe's FIX (windows)...

The code is below.

The problem is that I can not get the binds to trigger the validation
commands and the main table command

Control-C, Control-V, and Control-X work only in the visual without my R
data being changed.

Any help, tip or example is welcome and I thank you in advance for your
attention.

Thank you very much
