I found these callbacks:
Lua Code:
-- self is FOCUSED_QUEST_TRACKER
self:FireCallbacks("QuestTrackerInitialUpdate")
self:FireCallbacks("QuestTrackerTrackingStateChanged", self, true, trackType, arg1, arg2)
self:FireCallbacks("QuestTrackerRefreshedMapPins", journalIndex)
trackType, arg1, arg2 seem come from GetTrackedByIndex(i)

Lua Code:
FOCUSED_QUEST_TRACKER:RegisterCallback(cbName, cbFunc)
