Check for ItemStack with meta

Hey guys!
I created a custom Inventory, which works fine, now I got the same item 2 times, and Im using the meta to identify them. The first one is detected, althought the second isnt.

         + "Trickshot II");
     ArrayList<String> trickshot2_desc = new ArrayList<String>();
     trickshot2_desc.add(ChatColor.AQUA + "15% Chance to apply");
     trickshot2_desc.add(ChatColor.AQUA + "Blindness I on hit");
     trickshot2_meta.setLore(trickshot2_desc);
     trickshot2.setItemMeta(trickshot2_meta);

     levelup_elf.setItem(0, mobility);
     levelup_elf.setItem(18, trickshot);
     levelup_elf.setItem(19, trickshot2);
   }
}

Would be awesome if someone could help me

Now trying to check for the meta with displayname, works perfectly if there is only 1 item, but the second doesnt register

Code:

Inventory inventory = Bukkit.createInventory(null, 54, "TestInventory");

public ItemStack namedItem(Material material, String name) {
    ItemStack stack = new ItemStack(material);
    ItemMeta im = stack.getItemMeta();
    im.setDisplayName(name);
    stack.setItemMeta(im);
return stack;

public void setupInventory() {
    inventory.setItem(o, namedItem(Material.DIRT, "One"));
    inventory.setItem(o, namedItem(Material.DIRT, "Two"));
}

@EventHandler
public void onClick(InventoryClickEvent event) {
Inventory ci = event.getClickedInventory();
if(ci.getTitle() != null && ci.getTitle().equals(inventory.getTitle()) { //Don't know if title can be null so better check for it
  //Okay you can check this in so many ways, we already check the name of the inventory
  //so you could do the checks using the slots
  ItemStack stack = event.getCurrentItem();
   if(stack == null || stack.getType().equals(Material.AIR)) {
      return;
   }
   if(!stack.hasItemMeta()) {
      return;
   }
   ItemMeta im = stack.getItemMeta();
   if(!im.hasDisplayName()) {
      return;
   }
   String dn = im.getDisplayName();
   if(dn.equals("One") {
      //Stuff
   } else if(dn.equals("Two") {
      //Stuff
   }
}
}
