Solved Command doing nothing

Hello. I have writed command that must modify (or create if theres no one) two .yml files, but when i activate command it doesn't work.
Here is main class:

Code:

package me.kartofel374;

import org.bukkit.plugin.java.JavaPlugin;



public final class PlotOwners extends JavaPlugin {

    @Override
    public void onEnable() {
        // Plugin startup logic
        getLogger().info("Starting PlotOwners Plugin");
        this.getCommand("CreatePlot").setExecutor(new CreatePlotCommandExecutor(this));
    }

    @Override
    public void onDisable() {
        // Plugin shutdown logic
        getLogger().info("Stopping PlotOwners Plugin");
    }


}

Here is CreatePlotCommandExecutor.java:

Code:

package me.kartofel374;

import com.sun.javafx.binding.Logging;
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;

public class CreatePlotCommandExecutor implements CommandExecutor {

I tried with "CreatePlot" command and "createplot" command. all is fine in plugin.yml.
