Android.SQLite. Doesnt work uptade method

Other method works. Whats wrong? I use sql_helper.updateButton(new MyButton(number,width)), but is doesnt change my value

 public int updateButton(MyButton myButton) {

    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(COLUMN_BUTTON_NUMBER, myButton.getNumber());
    values.put(COLUMN_BUTTON_WIDTH, myButton.getWidth());



    return db.update(DATABASE_TABLE, values, COLUMN_ID + " = ?",
            new String[] { String.valueOf(myButton.getID()) });
}
