how to debug listView

[Michal Revivo]

Hi
I am testing the sample sushi web.
How I can debug the javacript and display the number of items for example.
It's running in chrome but nor in explorer.
I try to use F12 for explorer but didn't succeed to display the number of items.
Could you help ?
Thanks

var items = new kendo.data.DataSource({
      schema: {data: "GetProdByBizResult.RootResults"},
                        type: "json",
      serverFiltering: true,
      transport: {
                            read: {
        url:"http://www.yelotag.com/light/BizRef-Web-DomainService1.svc/JSON/GetProdByBiz",
        datatype:"json",
         data: {bizId: window.bizId,
          lg: window.lg
         }
        }
                        }
                    });
