[1.7.10] func_145881_a().setEntityName() not updating spawner display entity

[Mattasdqwe]

The title pretty much says it all

 

I am trying to change a spawner and while it does spawn the right entities after the change, the spinning display entity doesn't change unless it is hit with a sword in creative, or I relog.

 

here is the code:

String mobName = contents.stackTagCompound.getString("MobName");
TileEntity TEAbove = worldObj.getTileEntity(this.xCoord, this.yCoord + 1, this.zCoord);

	if(TEAbove instanceof TileEntityMobSpawner) {

			TileEntityMobSpawner TEspawner = (TileEntityMobSpawner)TEAbove;

			if(TEspawner.func_145881_a().getEntityNameToSpawn() != mobName) {

				TEspawner.func_145881_a().setEntityName(mobName);

			}

		}

It is minecraft rendering bug, nothing to do even with forge...

Sorry if this is out of place but is there any way to fix it or accomplish the same thing?

Technically, you need to force update WorldRenderer that includes this block. That's all...
