            var  Person = Backbone.Model.extend();

            var person = new Person();
            document.write("<b> Before setting unique identifier of model Person : </b>",person.id);
            document.write("<br>");
            document.write("<b> Before setting unique identifier of model Person, CID: </b>",person.cid);

            document.write("<br>");
            var person = new Person({id: 1});
            document.write("<b> After setting unique identifier of model Person : </b>",person.id);
            document.write("<br>");
