Villager citizen api

How can I make npcs talk when they get right-clicked using the Citizen API ?
I'm trying to make npcs talk when they get right-click.

 

Code:

@EventHandler
  public void onPlayerRightClick(PlayerInteractEntityEvent e) {
  if(e.getRightClicked() instanceof Villager){
      Entity mob = e.getRightClicked();
      Player p = e.getPlayer();
      if(mob.getCustomName()==null){
      return;
      }
      if ((mob.getCustomName().equalsIgnoreCase("My name is John"))) {
          p.sendMessage("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA@@@@@@@@@");
          e.setCancelled(true);
     }
     }
  }

 

This is just using the Bukkit/Spigot API, he wants to use the Citizens API

 

But Citizens API does not extends bukkit?
'-'
Just change the My name is John to the name of the citizen '-'
