Settings page question

[flart]

in the start() of KSPAddon I have
settings = HighLogic.CurrentGame.Parameters.CustomParams<Mod>();
A then I just using settings.mycoolbool in the lateUpdate()

Useful cool feature
When user opens mod settings in the difficulty section dialog and changes settings, 
setting.mycoolbool right away is changed in lateUpdate() and user sees 
changed stuff in the flight.

Problem
user changes some settings, and then press ESC or cancel instead of ok or accept. 
Checkboxes on the settings page are reverted to previous state as intended, but on the flight scene options are stuck to the new state
and if user opens the dialog again, then checkboxes changing do not make difference to the flight scene, even with the pressing settings accept button. Only f5-f9 helps
