[SOLVED]Collide doesn't work (I must be blind)

[FlawlessHappiness]

This function won't call.
No errors. No alerts.

What should happen is easy:
Door collides with area -> Monster gets active -> Monster follows pathnode -> Monster disappear

Script:

void OnStart()
{
AddEntityCollideCallback("castle_arched01_1", "AreaOpenDoorGrunt", "OpenDoorGrunt", true, 0);

AddEntityCollideCallback("servant_grunt_3", "AreaMonsterDisappear_1", "MonsterDisappear_1", true, 0);

}


void OpenDoorGrunt(string &in asParent, string &in asChild, int alState)
{

AddDebugMessage("CALLING SCRIPT", false);

if(GetLocalVarInt("MonsterIsActive") == 1)
{
return;
}

if(GetLocalVarInt("StopMonster") == 1)
{
return;
}
AddDebugMessage("MONSTER ACTIVE", false);
SetEntityActive("servant_grunt_3", true);
AddEnemyPatrolNode("servant_grunt_3", "PathNodeArea_100", 0, "");
SetLocalVarInt("MonsterIsActive", 1);
SetEntityActive("AreaOpenDoorGrunt", false);
}


void MonsterDisappear_1(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("servant_grunt_3", false);
PlaySoundAtEntity("", "Enabled.snt", "AreaStopMonster", 0, false);
}

None of the 2 debug messages get called. What am I missing?
