Subject: [PATCH] Dialog must listen for changes to the param names

Otherwise the second keystroke made while changing parameter names will cause
an error. I think this code previously assumed the change only happened once,
rather than on-keystroke.

Bug: T142889
Change-Id: I0e9c096a053667c51bbce74ee3ce1bd573ae7d49
