I noticed that you've opened a support ticket on the same topic. I will summarize our communication also here for the benefit of our community.
In case you added the HTML5 MVC Report Viewer through the Item template, then the REST service should be automatically created. If there is nothing on the page, I suspect that there is something wrong with the routes or maybe you navigate to the wrong page. You can also check for any errors with the browser's console and use Fiddler to follow the exact requests from the viewer to the service.
Our MVC demo can be found at C:\Program Files (x86)\Progress\Telerik Reporting <VERSION>\Examples\CSharp.
