PowerBI Custom Visuals: Show Dataview Icon doesn't response

Question

I am following the Microsoft tutorial to study PowerBI custom visuals. However, I got stuck on the show dataview icon. In the tutorial, when developer clicks the show dataview icon, it should return the following:Microsoft tutorial screenshot. But what I got is nothing if I click the show dataview icon: My powerBI screen shot.

To fix this, I tried to restart the session, re-build the project... but none of them works.
