Solved Nothing happens ingame

I'm working on a remake of the mcpvp salvaging plugin. What I want in the code is that if you're holding a diamond helmet, and rightclick a diamondblock with a furnace to it, you will get 5 diamonds. No errors are on the console, but nothing happens when I rightclick the diamondblock

Main:

Code:

package com.epixel.salvaging;

import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

import com.epixel.salvaging.diamond.DHelmet;

public class Main extends JavaPlugin {

    public void onEnable() {
        getLogger().info("Salvaging has been enabled!");

    }

    public void registerEvents() {
        PluginManager pm = getServer().getPluginManager();

        pm.registerEvents(new DHelmet(), this);
    }

    public void onDisable() {
        getLogger().info("Salvaging has been disabled!");

    }

}

DHelmet:

package com.epixel.salvaging.diamond;

import org.bukkit.Material;
import org.bukkit.block.BlockFace;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;

public class DHelmet implements Listener {

    @EventHandler
    public void onSalvage(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
            if (event.getClickedBlock().getType() == Material.DIAMOND_BLOCK
                    && event.getClickedBlock().getRelative(BlockFace.DOWN).getType() == Material.FURNACE
                    || event.getClickedBlock().getRelative(BlockFace.SOUTH).getType() == Material.FURNACE
                    || event.getClickedBlock().getRelative(BlockFace.UP).getType() == Material.FURNACE
                    || event.getClickedBlock().getRelative(BlockFace.NORTH).getType() == Material.FURNACE
                    || event.getClickedBlock().getRelative(BlockFace.WEST).getType() == Material.FURNACE
                    || event.getClickedBlock().getRelative(BlockFace.EAST).getType() == Material.FURNACE) {
                if (player.getItemInHand().getType() == Material.DIAMOND_HELMET) {
                    ItemStack diamond5 = new ItemStack(Material.DIAMOND, 5);
                    player.getInventory().remove(player.getItemInHand());
                    player.getWorld().dropItem(player.getLocation(), diamond5);
                }
            }
        }
    }
}

 

@Epixel
Well, you create a "registerEvents" (which by the way is quite unnecessary) but you never call it.

 

Thank you haha Im retarded.
