Spawning in a fish hook/line

Ok guys, basically I want it so when you left click a lead it spawns a fishhook entity.
For some reason this code does not work. Can someone help me? In game when I left click the lead it does not fire the fishing hook. Thanks!

Code:

@EventHandler
public void onGrapplerthingy(PlayerInteractEvent e){
    Player p = e.getPlayer();
    Action a = e.getAction();
    Vector vector = p.getEyeLocation().getDirection();
    if(grappler.contains(p.getName()) && p.getItemInHand().getType() == Material.LEASH){
        if(a == Action.LEFT_CLICK_AIR || a == Action.LEFT_CLICK_BLOCK){
    Entity hook = p.getWorld().spawnEntity(p.getEyeLocation(), EntityType.FISHING_HOOK);
    vector.multiply(3);
    vector.setY(1.0F);
    hook.setVelocity(vector);
 
    }
    }
}
