Firstly, did you transcribe this with siri? lol.
So its an iPhone 4S, but you are only getting the notifications bubble and no banner or lock screen notifications?

iPhone has a few settings where the notifications can be tailored to suit each app.

try going to Settings > Notifications,
Now look for the Facebook app, and make sure the notification settings have "show in lockscreen" and "banners" selected.
these will allow the facebook app to notify you as you wanted.
