Fix the unclickable tertiary navigation arrow after AJAX refresh of cloud service provider tables

@yas, please review this patch. This fixes the pagination/ajax refresh issue with the tertiary menu. The issue is that the $('#right-button').click() was firing multiple times, making it seem like the menu is not opening up. I think that is because after each AJAX refresh from pagination, the $('#right-button').click() re-binds agains and starts to fire multiple times.

The fix is to add a $('#right-button').once().click to make sure it fires once per click.
