Network Disconnecting

Hey i am new to multiplayer games and i was following the multiplayer tutorial and it works fine except for the disconnecting part. I have the script:

 var me : Transform;
 
 function OnNetworkLoadedLevel () 
 {
     Network.Instantiate(me, transform.position, transform.rotation, 0);
 }
 
 function OnPlayerDisconnected (player : NetworkPlayer) 
 {
     Network.RemoveRPCs(player, 0);
     Network.DestroyPlayerObjects(player);
 }

Whenever i disconnect the cube doesnt get destroyed, can someone help me on why the OnPlayerDisconnected isnt being called? Thanks
