Enchantment not appearing to be added?

I have a listener, and after enough blocks are broken, an enchantment is added to the tool.
I have:

Code:

ItemStack is = p.getItemInHand();
is.addEnchantment(Enchantment.DIG_SPEED, 1);

I also entered a debug line, and the code IS being executed, but the tool doesn't appear to change.
If it may matter at all, I have a custom lore & display name.

Thanks

 

Trevor1134 When you are changing the custom lore and display name you can just take the metaData you use and do something like this

Code:

 ItemStack testEnchant = new ItemStack (Material.BOW, 1);
        ItemMeta testEnchantMeta = testEnchant.getItemMeta();
        testEnchantMeta.addEnchant(Enchantment.ARROW_FIRE, 10, true);
     //add colors and what not
        testEnchant.setItemMeta(testEnchantMeta);

Although it's hard to tell with the amount of information given it could be that you are adding the enchantment, then changing the meta and then it removes the previous data with the enchantment.
