title: Ionic 2 OnPause and OnResume the previous page is not maintained?
body: <p>I am using the <code>sidemenu</code> template.</p>
  
  <blockquote>
    <p>ionic start tempName sidemenu --v2 --ts</p>
  </blockquote>
  
  <p>I opened Page Two and then pressed the back button of mobile the application went to hidden. I hope in this case <code>onPause</code> activity is used.</p>
  
  <p>When I resume again the Page Two is changed as Page One. When <code>onResume()</code> activity the previous state is not restored.</p>
  
  <p>Can you please help me to resolve this.?</p>
