This is code "each person in people" — once you go down the path of doing that kind of thing, the next thing people will ask for are filters, etc. and eventually half your business logic is in the "template" and half in the view code.
IMOH, handlebars is a lazy version of mustache where the developer using it sacrifices maintainability and encapsulation. Which is probably ok for most apps that don't grow beyond a single developer.
