<div ng-app="model" ng-controller="MainCtrl">
  This scope value <input ng-model="name">, label: "{{label}}"
  <ul>
    <li>With new isolate scope (label from parent):
      <my-directive-with-scope ng-model="name"></my-directive-with-scope>
    </li>
    <li>With new child scope:
      <my-directive-with-child-scope ng-model="name"></my-directive-with-child-scope>
    </li>
    <li>Same scope:
      <my-directive-without-scope ng-model="name"></my-directive-without-scope>
    </li>
    <li>Replaced element, isolate scope:
      <my-replaced-directive-isolate ng-model="name"></my-replaced-directive-isolate>
    </li>
    <li>Replaced element, child scope:
      <my-replaced-directive-child ng-model="name"></my-replaced-directive-child>
    </li>
    <li>Replaced element, same scope:
      <my-replaced-directive ng-model="name"></my-replaced-directive>
    </li>
  </ul>
  <p>Try typing in the child scope ones, they copy the value into the child scope which breaks the link with the parent scope.
  <p>Also notice how removing jQuery makes it so only the new-isolate-scope version works.
  <p>Finally, note that the replace+isolate scope only works in AngularJS >=1.2.0
