lok: sc: address and formula text field empty on creating a new view

When the client starts the address and formula text field were empty
because the updating callbacks occurred before the view callback
handler had been registered.
So a new method `afterCallbackRegistered` has been added in order to
perform any needed updating/initialization soon after the view
callback handler has been registered.
