title: How to change the Back Button Text on Xamarin.Forms
body: <p>I have been trying to change the text of the back button in Xamarin.Forms without luck. </p>
  
  <p>I tried already this code with no luck:</p>
  
  <pre><code>NavigationPage.SetBackButtonTitle(this, "");
  </code></pre>
  
  <p>I'm using a <code>MasterDetailPage</code>.</p>
  
  <p>I tried to add the code into the constructor of the XAML cs file.</p>
  
  <p>Libraries used: PRISM 6.2.0, Xamarin Forms 2.3.1.114</p>
  
  <p>Any suggestion or idea?</p>
  
  <p>Thanks in advance</p>
