How to show multiple fields in popups with a views_geojson layer?

I have finally gotten up and running with the basic features I need for my map: custom markers and popups. I'm trying to show 4-7 fields in the popup about the individual locus represented by the popup. By default, views geojson, only maps two fields, a title and description. So, how can I pull the rest of the data from my geojson layer into the popup? I'm using OL3 - dev, and all the rest are all stable versions of the dependencies.
