title: AngularJS/Jade not working with the ng-app directive
body: <p>i tried to build a small prototype Webserver (NodeJS/Jade) to learn AngularJS. Until now i only coded with NodeJS/Javascript/JQuery. I made these following blocks:
  The short expression {{ 843 / 42 }} is calculated correctly only when ng-app='' (without a specific name). When i use ng-app='myApp'  the expression is outputed directly without calculcation. The two text boxes are not filled in with John Doe in botuh cases. Can anyone help me or give me an advise.</p>
  
  <p>layout.jade</p>
  
  <pre><code>doctype html
  html(ng-app='')
    head
      title= title
      link(rel='stylesheet', href='/stylesheets/style.css')
      script(src='/javascripts/angular/angular.js', type='text/javascript')
      script(src='/javascripts/angular/angular-resource.js', type='text/javascript')
      script(src='/javascripts/jquery-2.1.4.min.js', type='text/javascript')
      script(src='/javascripts/index.js', type='text/javascript')
  
      block scripts
    body
      block content
  </code></pre>
  
  <p>index.jade</p>
  
  <pre><code>extends layout

  <p>Index_Load:</p>
