Adapting Data for Display in a List Code challenge 2/2

hello, I dont understand what i did wrong that the syntax dosn't work?

Inside 'onPostExecute()', set the member variable 'mStatus' to the value passed into 'onPostExecute()'. Then call the 'updateStatusLabel()' method of 'CustomActivity'.

import android.os.AsyncTask;
import android.os.Bundle;

public class CustomActivity extends Activity {

    public String mStatus;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom);
        CustomAsyncTask task = new CustomAsyncTask();
        task.execute();
    }

    protected void updateStatusLabel() {
        super.updateStatusLabel();
    }

    protected class CustomAsyncTask extends AsyncTask<Object, Void, String> {   
        @Override
        protected String doInBackground(Object... params) {
            // Imagine this is some code to do some work
            return "Done!";
        }
 @Override
    protected void onPostExecute(String result){
      mStatus = result;
      updateStatusList();
  }
 }
}

The reason why it wasn't working is because on the last line he called "updateStatusList()" instead of "updateStatusLabel()".
