this sample does not run properly when i run it locally

http://localhost:20776/samplesbrowser/grid/sl/#/icustomtypeprovider-binding

both users come up with the same age and married flag, ie they both have 45.  seems like a bug?

   Customer cust01 = new Customer { FirstName = GridStrings.ictp_Mary, LastName = GridStrings.ictp_Smith }; // { FirstName = "Mary", LastName = "Smith" };
            cust01.SetPropertyValue("Age", 40);
            cust01.SetPropertyValue("Married", true);

            Customer cust02 = new Customer { FirstName = GridStrings.ictp_John, LastName = GridStrings.ictp_Smith }; // { FirstName = "John", LastName = "Smith" };
            cust02.SetPropertyValue("Age", 45);
            cust02.SetPropertyValue("Married", true);

            customers.Add(cust01);
            customers.Add(cust02);
