[ionitron-bot]

The Problem
I push the Root Page to Page2 that supports a side menu, the issue is that when it opens Page2 it shows the back button and hides the menu button for that I've tried to add hideBackButton to Page2 in order to see the menu button but I both the back button and menu button disappeared!

Here is my current code:

  <ion-navbar hideBackButton>
       <button menuToggle start>
       <ion-icon name="menu"></ion-icon>
       </button>
 </ion-navbar>

What behavior are you expecting?

Should hide the back button, and show the menu button.
