PlayerController failed to call PostBeginPlay()

[dprat0821]

Hi,
I've no idea why PostBeginPlay() cannot work in my PlayerController

class MyGamePC extends GamePlayerController;

simulated event PostBeginPlay(){
        super.PostBeginPlay();
	//===This Doesn't work!!!!
	InitParameters();
	
	WorldInfo.Game.Broadcast(self,"Game Begin!!");
	
}

event InitInputSystem()
{
   Super.InitInputSystem();
   //.....
   //When I put it here, it works.
  InitParameters();
}


function InitParameteres(){
    //balabala....
}

Thanks for you advices.
