Vadim Zeitlin 8fcedbed7b Remove event table from static page in the widgets sample
The code was confusing as it used Bind() for some handlers, event table
for some others and, for the 3 buttons in the middle column, it actually
managed to use both.

Get rid of the event table completely to make this more clear.
