In other words, you should update all apps when they are available - else you will continually see the red badge on your App Store icon. And, you cant NOT update an app; if it's on your iPad and needs an update, you will need to update it. The only way to avoid this is to delete the app from your iPad.
Sorry to not be of better help. :)
