blockplaceevent not working

I'm trying to get it so that when you place a block of tnt it replaces it with a primed tnt so that it explodes without you having to light it but it doesn't seem to work right, I feel like I'm doing everything right, does anyone know where the problem is?

Code:

package me.jstN0body.selflightingTNT.event;

import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.block.Block;
import org.bukkit.entity.EntityType;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;

import me.jstN0body.selflightingTNT.Main;

public class OnPlaceTNT implements Listener {

    @SuppressWarnings("unused")
    private Main plugin;
  
  
    public OnPlaceTNT(Main plugin) {
        this.plugin = plugin;
      
        Bukkit.getPluginManager().registerEvents(this, plugin);
    }
  
    @EventHandler
    public void onTntPlaced(BlockPlaceEvent event) {
        Player player = event.getPlayer();
        World world = player.getWorld();
        Block placedBlock = event.getBlock();
        Material blockType = event.getItemInHand().getType();
        EntityType primedTnt = EntityType.PRIMED_TNT;
        if (blockType == Material.TNT) {
            placedBlock.setType(Material.AIR);
            world.spawnEntity(placedBlock.getLocation(), primedTnt);
        }
    }
}

 

@timtower do you mean an instance in the main class because I have that.

 

@timtower It should be, I did a previous plugin with events the same way that I did this one and it works fine.

 

Ok it seems to not be calling the event correctly, I put 2 print statements one in onEnable() and one in the BlockPlaceEvent thing, the one for onEnable displays but not the one in the event
below is my main class, am I calling the class incorrectly?

Code:

package me.jstN0body.selflightingTNT;

import org.bukkit.plugin.java.JavaPlugin;

import me.jstN0body.selflightingTNT.event.OnPlaceTNT;



public class Main extends JavaPlugin {
    @Override
    public void onEnable() {
        System.out.println("onEnable working");
       
        new OnPlaceTNT(this);
    }
}

 

@timtower ok idk how it's working now
