Angular + Jade issue with express routing

Question

I've encountered an issue with while working with Angular & Jade. Everything was working fine, routing in express was working (get & post). I noticed that when I added ng-app to the html or body tag in the jade template, post was not working anymore. Client side seems to be working, templates are loading, but once I try hitting the submit button the a form, post requests aren't being made, only gets. I even try to console log on the post in app.js and it doesn't seem to get there.

Not sure if it may even be related to the submit button just not making the submit request on the form because when I click it, nothing happens so possibly a binding issue? But if I remove the ng-app, everything starts working fine.

Try ng-submit for angular. angular providedes you ng-submit option for forms submissions.
Edit also post your network stats from console. it will help
