Solved PlayerInteractEvent help

Hi, I've got a class that should listen for people clicking on a stick called §cWand, and if so, summon a fireball. However, absolutely nothing happens, no errors, nothing.

Code (Text):

package me.piggypiglet.warrior;

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 static org.bukkit.Material.*;
import static org.bukkit.entity.EntityType.*;
import static org.bukkit.event.block.Action.*;

public class MageEvent implements Listener {
    @EventHandler
    public void onPlayerInteractEvent(PlayerInteractEvent e) {
        Player p = e.getPlayer();
        Action a = e.getAction();
        if (a == RIGHT_CLICK_AIR || a == RIGHT_CLICK_BLOCK || a == LEFT_CLICK_AIR || a == LEFT_CLICK_BLOCK) {
            if (e.getItem().getType() == STICK) {
                if (e.getItem().getItemMeta().getDisplayName().equals("§cWand")) {
                    return;
                }
            }
        }
        p.getWorld().spawnEntity(p.getLocation(), FIREBALL);
    }
}

Any help is appreciated. I am also a beginner in plugin development but I will do my best to understand responses.

EDIT: I have registered it in main, in onenable by
getServer().getPluginManager().registerEvents(new MageEvent(), this);

EDIT 2: Just tried this,

Code (Text):

        if (a == RIGHT_CLICK_AIR || a == RIGHT_CLICK_BLOCK || a == LEFT_CLICK_AIR || a == LEFT_CLICK_BLOCK) {
            if (p.getInventory().getItemInMainHand().getType() == STICK) {
                if (p.getInventory().getItemInMainHand().getItemMeta().getDisplayName().equals("§cWand")) {
                    return;
                }
            }
        }

Didn't work either.

 

Fixed, Thanks @2008Choco

 

@md_5 Good idea, fairly silly of me to not put the fix in here since I've suggest many people to do the same.

Fixed by changing

Code (Text):

        if (a == RIGHT_CLICK_AIR || a == RIGHT_CLICK_BLOCK || a == LEFT_CLICK_AIR || a == LEFT_CLICK_BLOCK) {
            if (e.getItem().getType() == STICK) {
                if (e.getItem().getItemMeta().getDisplayName().equals("§cWand")) {
                    return;
                }
            }
        }
        p.getWorld().spawnEntity(p.getLocation(), FIREBALL);

to

Code (Text):

        if (a == RIGHT_CLICK_AIR || a == RIGHT_CLICK_BLOCK || a == LEFT_CLICK_AIR || a == LEFT_CLICK_BLOCK) {
            if (e.getItem().getType() == STICK) {
                if (e.getItem().getItemMeta().getDisplayName().equals("§cWand")) {
                    p.getWorld().spawnEntity(p.getLocation(), FIREBALL);
                }
            }
        }
