I am trying to add end ores. for some reason they just wont generate period. I cant seem to find a solution

This is my init class

import net.minecraft.block.Blocks;
import net.minecraft.world.biome.Biome;
import net.minecraft.world.gen.GenerationStage;
import net.minecraft.world.gen.feature.ConfiguredFeature;
import net.minecraft.world.gen.feature.Feature;
import net.minecraft.world.gen.feature.OreFeatureConfig;
import net.minecraft.world.gen.feature.template.BlockMatchRuleTest;
import net.minecraftforge.common.world.BiomeGenerationSettingsBuilder;
import net.minecraftforge.event.world.BiomeLoadingEvent;

public class FeatureInit {

    public static final ConfiguredFeature<?, ?> VIBRANIUM_ORE = Feature.ORE.configured(
            new OreFeatureConfig(new BlockMatchRuleTest(Blocks.END_STONE), BlockInit.VIBRANIUM_ORE.get().defaultBlockState(), 4)) //vein size
            .range(100).squared() //maximum y level where ore can spawn
            .count(13); //how many veins maximum per chunk

    public static void generateOre(final BiomeLoadingEvent event) {
        BiomeGenerationSettingsBuilder generation = event.getGeneration();
        if (event.getCategory().equals(Biome.Category.THEEND)) { //OPTIONAL IF STATEMENT allows you to generate ores in specific biome types for example icy biomes
            generation.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, VIBRANIUM_ORE);
        }
    }
}

And this is in the original class

    //Ore Generation
    private void setup(final FMLCommonSetupEvent event) {
        // some preinit code
        LOGGER.info("HELLO FROM PREINIT");
        LOGGER.info("ORE BLOCK >> {}", BlockInit.VIBRANIUM_ORE.get());
        MinecraftForge.EVENT_BUS.addListener(EventPriority.HIGH, FeatureInit::generateOre);
}

I am confused as to why this doesn't work. Any info would help

"MinecraftForge.EVENT_BUS.addListener(EventPriority.HIGH, FeatureInit::generateOre);" 

It should not be in "FMLCommonSetupEvent".

 

Solution:

The main: 

@Mod(Example.modid)
public class Example {
    public static final String modid = "examplemod";
    private static final Logger LOGGER = LogManager.getLogger("examplemod");
    public static final CreativeModeTab examplemod = new ExampleTab();

    public Example() {
        IEventBus modEventbus = FMLJavaModLoadingContext.get().getModEventBus();

        ExampleBlocks.BLOCKS.register(modEventbus);
        ExampleItems.ITEMS.register(modEventbus);

        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::clientSetup);
      
      	MinecraftForge.EVENT_BUS.addListener(EventPriority.HIGH, FeatureInit::generateOre);

        ModLoadingContext.get().registerConfig(Type.COMMON, GWorldConfig.SPEC, "example-common.toml");

        MinecraftForge.EVENT_BUS.register(this);
    }
	etc.........
}
