Pircbotx channel setMode() not working in main() method

Question

I'm trying to set mode to an IRC channel but PircBotX doesn't seems to execute the command when called in the main method. The command executes when I send the message (!setRModePlus) that I have set up in the code. Where am I wrong with my code?

import org.pircbotx.Channel;
import org.pircbotx.Configuration;
import org.pircbotx.PircBotX;
import org.pircbotx.hooks.ListenerAdapter;
import org.pircbotx.hooks.types.GenericMessageEvent;

public class MyListener extends ListenerAdapter {

static Channel channel = null;
static PircBotX bot = null;

@Override
public void onGenericMessage(GenericMessageEvent event) {

   if (event.getMessage().startsWith("!setRModePlus")) {
         channel = bot.getUserChannelDao().getChannel("#mychannel");
         channel.send().setMode("+R");
    }
    if (event.getMessage().startsWith("!setRModeMinus")) {
         channel = bot.getUserChannelDao().getChannel("#mychannel");
         channel.send().setMode("-R");
    }
}

public static void main(String[] args) throws Exception {
    //Configure the bot
    Configuration configuration = new Configuration.Builder()
            .setName("myname")
            .addServer("myserver")
            .setNickservPassword("mypassword")
            .addAutoJoinChannel("#mychannel") 
            .addListener(new MyListener()) 
            .buildConfiguration();

    //Create  bot with the configuration
    bot = new PircBotX(configuration);
    bot.startBot();
    channel = bot.getUserChannelDao().getChannel("#mychannel");
    channel.send().setMode("+R");



}

Thank you for any help you can offer. Sorry for my English.

Problem solved now. I added onConnect method and send the command like this

 public void onConnect(ConnectEvent event) {

        event.getBot().send().mode("#mychannel", "+R");
        event.getBot().send().mode("#mychannel", "-R");


}
