Crazy Auction custom sell price

In CA you can only write a price in command /ca sell %price%.
For my server, i tried to make it easier with npc you clicking on, and enter your price, but id doesnt work at all. Not even messages in the log.

In general, i tried to create this:

if executed /youridea

send message "enter price"
get player's message
execute "/ca sell" + player's message
​

main class:

Code:

package me.deginech.uridea;

import me.deginech.uridea.sender.youridea;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerRespawnEvent;
import org.bukkit.plugin.java.JavaPlugin;

public final class URIDEA extends JavaPlugin implements Listener{

    @Override
    public void onEnable() {
        System.out.println("You pick ou the wrong door.");
        getCommand("youridea").setExecutor(new youridea());
    }
    @Override
    public void onDisable() {
        System.out.println("My battery is low, and it's getting dark");
    }
}

another one:

Code:

package me.deginech.uridea.sender;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.AsyncPlayerChatEvent;

public class youridea implements CommandExecutor, Listener {


    @EventHandler
    public boolean onCommand(AsyncPlayerChatEvent event, CommandSender sender, Command command, String label, String[] args){
        if(sender instanceof Player){
            Player player = (Player) sender;
            player.sendMessage("§6Enter your price.");
            String msg = event.getMessage();
            event.setCancelled(true);
            player.performCommand("ca sell" + msg);
        }
        return false;
    }

    @Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        return false;
    }
}

Please, tell me, what i did wrong?

 

@deginech You're combining the event method with the command method, you can't do that. You should read up on command and event tutorials.
