Solved Change Spawner Type on Block Place

I've searched the forums (probably not hard enough) and can't seem how to change the creature/entity spawned in a mob spawner in the BlockPlaceEvent. I know that the spawner will not change its type in this event, and I would like to know how to 'wait' a tick to reset it.

Here is my current code in an event listener, which [should] set the spawner to spawn primed TNT, making an excellent land mine:

Code:

    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event){
        Player player = event.getPlayer();
        if (event.getBlock().getType() == Material.MOB_SPAWNER){
                Block bl = event.getBlock();
                CreatureSpawner s = (CreatureSpawner) bl.getState();
                s.setSpawnedType(EntityType.PRIMED_TNT);
                player.sendMessage(ChatColor.GOLD+"Primed TNT Spawner placed!");
                player.sendMessage(s.getSpawnedType().getName());
            }
        }
    }

But I need to know how to wait a tick and set it then.
All help would be appreciated.

Thanks, guys, especially Muddr, I wasn't so familiar with scheduled tasks.

But another thing: I am not sure how to get the event's block and player through a delayed event.

EDIT: Using a repeated task (used for other things) to also control spawners.
