Help with Entity

So, i'm trying to control an enderdragon and it sort of works.
I have used this as my e() class to make it face where i am facing:

Code:

@Override
    public void e(float one, float two) {
        this.lastYaw = this.yaw = this.passenger.yaw;
        this.pitch = this.passenger.pitch * 0.5F;
       
        this.b(this.yaw, this.pitch);
        this.aO = this.aM = this.yaw;
        super.e(one, two);
        return;
    }

and I'm using this to fly him

Code:

@EventHandler
      public void onPlayerMove(PlayerMoveEvent e) {
        Player p = e.getPlayer();
        double defaultspeed = 1.0;
        double d = defaultspeed;
        if (p.getVehicle() != null)
        {
            Entity v = p.getVehicle();
            Vector f = p.getEyeLocation().getDirection().multiply(d);
            v.setVelocity(f);
            v.teleport(
              new Location(v.getWorld(), v.getLocation().getX(), v
              .getLocation().getY(), v.getLocation().getZ(), p
              .getEyeLocation().getPitch(), p.getEyeLocation().getYaw()));
            p.setFallDistance(0.0F);
            v.setFallDistance(0.0F);
        }
      }

It goes where I want him to, but he doesn't face that way. It works for any other mob than this.
Is there any way I can make him face the way i'm looking?

Please don't link me to this http://bukkit.org/threads/tutorial-1-7-5-wasd-entity-riding.163019/

I've already tried it. Any help?

It's different for an enderdragon
