Without more information/context it is hard to diagnose what is going on. From the top of my head, two things might be happening:
- Is your popovers ever triggered? I see many attributes but no trigger for the popovers to fire.
- Is the popover generation code in a document-ready function? If not it could be rendering before the DOM is loaded.
- (experimental) What happens if you put some plain text into the popover content?
Hope this helps!
