Have you checked if your setFuncs get executed as expected?

function EZTest_Config.DismountCheck.setFunc(state)
  print("-----> DismountCheck.setFunc", state)
  EZTestData.Config_Dismount = state
  lib.ApplyLayout()
end

PS: You also know that changes are only written back to the saved variable files once you /reload or exit the game, right?
