 * I am trying to learn how to create a plugin and in doing that i was trying to
   use register_setting function.
    When i am using it without the 3rd parameter 
   it works fine and plugin options are saved successfully in options.php.
 * But when i am trying to use 3rd parameter which is the callback function its 
   not accessing at all and at that time no options are saved as well.
 * Here is the code i am using.
 *     ```
       <?php
       /*

               $this->options = get_option('jw_plugin_options');

           }
