Absolutely. Honestly it seems to fly really far with the node youngsters who want to code all night for some reason. What you're talking about is event delegation. It's a one liner practically, but shh, we're talking about "architecture" now.
AngularJS is an MVVM framework. It's fairly new to JS and front end web development, but not that new for UI development in general (it's been around since 2005 in WPF and used in Silverlight and Flex applications, and possibly others). It isn't just 'event delegation'.
