Multiple Items in Bootstrap Carousel from Angular.js 1.6

Presently, I am attempting to display 4 items per slide. I manage to populate the carousel with a total of 8 items. Your task is to write the logic to split 8 items into 4 items per slide. Something like this example: [login to view URL] I believe it can be coded much simpler than the example. I am using the older version of angularjs. Your are required to work on this task via remote desktop. This task is very simple. You are only required to work on the front-end only.
