title: RegisterJsObject CefSharp not work
body: <p>I have that problem whith CefSharp and js communication. 
  This is my structure. In my MainWindow.xaml.cs I have:</p>
  
  <pre><code>chromium = new CefSharp.Wpf.ChromiumWebBrowser();
  chromium.RegisterJsObject("jsInterface", new jsMapInterface());
  </code></pre>
  
  <p>where <strong>jsMapInterface</strong> is a public class with its methods.</p>
  
  <p>In my html/js folder, I call a C# method with:</p>
  
  <pre><code>window.jsInterface.myTest();
  //jsInterface.myTest();  //I have tested twice
  </code></pre>
  
  <p>where myTest() is a method inside <strong>jsMapInterface</strong> class but nothing happens. Where is my mistake?</p>
  
  <p>Thanks in advise.</p>
