title: How can I push or replace page inside a Navigator Onsen UI?
body: <p>i am developing an app with cordova + Onsen UI.
  I would like to know how can I use the .popPage() method to a navigator content.
  Is it possible? I read and read and read but did not understood exactly the mean for a navigator.
  I tried to get all this content off from navigator and put into a new page, then I defined the main page to this new I've created. But had no success too.
  Look the code:</p>
  
  <pre><code>&lt;ons-template id="home.html" style="background:#fff;"&gt;
    &lt;ons-navigator var="myNavigator" title="Navigator"&gt;
  
        &lt;ons-page id="content-home" class="fill"&gt;
          &lt;div class="gradient"&gt;
  </code></pre>
  
  <p>So how can I use push or replace function for a page inside the navigator?
  Thank you.</p>
