Hi this is just a future notice to myself and other frustrated devs. So if someone else finds his self wondering why i can not have select option attributes when everything else is done by the book and no data-[vars] are passed to select option list.
The answer is simple . Please check if you have installed this module https://www.drupal.org/project/jump_menu .
It simply overrides all the other "attributes" from all the other modules. So you never get to see your custom attributes because of this module :)
Hope that helps someone one day :)
