title: MoSync - addTo or addChild?
body: <p>To keep it short and simple, I'm doing a mosync nativeUI javascript project. Here's part of my code:</p>
  
  <pre><code>var myScreen = mosync.nativeui.create("Screen" ,"myScreen", {
                 "title": "My Screen"
            });             
            //Create a Button
             var myButton = mosync.nativeui.create("Button" ,"myButton",
             {
                //properties of the button
                "width": "FILL_AVAILABLE_SPACE",
                "text": "Click Me!"
             });
  
  
          var myLayout = mosync.nativeui.create("VerticalLayout", "myLayout", 
          {
              "data-width":"FILL_AVAILABLE_SPACE", 
              "data-height":"FILL_AVAILABLE_SPACE"
          });
  
          myLayout.addTo("myScreen");
  
          //myButton.addTo("myLayout");
          myLayout.addChild("myButton");
  </code></pre>
  
  <p>This works, I get a new tab in my screen and the button is there.</p>
  
  <p>But, if I change the last two lines and use addTo instead of addChild for adding the button to the layout, the button is not displayed.</p>
  
  <p>Shouldn't the myButton.addTo("myLayout") be the same as myLayout.addChild("myButton")??</p>
