You are going a fairly long winded way about it.
Rather than generating events use the Text/Entry
widget methods directly.

Check the documentation for the following methods:

Text.get(....)   # copy
Text.selection_get(...) # copy a selection
Text.delete(...)  # cut
Text.insert(...)  # paste

To control selections look at the tag methods,
but that is more complex.

These should be in the create function. You don't need
to configure the command every time you show the menu.

You should only need to call the tk.call() method very,
very rarely, there is usually a more direct way to do things.

Shouldn't these Entries have a parent?
