Not getting a callback to native UserControl on cordova app WP8
<p>I am creating a cordova application with a WP8 native page. I am calling the native page in the js file by making the call,    </p>

<pre><code>WL.NativePage.show(nativePageClassName, backFromNativePage, params);
</code></pre>

<p>The native page is a usercontrol (as mentioned in the <a href="https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/7.0/adding-native-functionality/windows-phone-8-using-native-pages-hybrid-applications/" rel="nofollow">documentation</a>) and I have implemented augmented reality in the usercontrol. Code below:</p>

<pre><code>&lt;ARControls:ARDisplay x:Name="ARDisplay"&gt;

   &lt;!-- Shows the content from camera--&gt;
   &lt;ARControls:VideoPreview x:Name="VideoPreview"/&gt;
   .
   .
   .
&lt;/ARControls:ARDisplay&gt;
</code></pre>

<p>The camera opens when this usercontrol is called. But once I do a forward navigation from this usercontrol and then clicks back button, the usercontrol is visible but the camera doesn't get opened and I do not get a callback to this usercontrol on backkeypress. How can this be handled? Any help would be much appreciated.</p>
