Knockout validation group undefined or unable to location errors in MVC

Question

I'm trying to work on knockout and unable to validate using knockout validation plugin. [EDIT: update fiddle] sample fiddle: jsfiddle.net/EHDD8

           var CustVM = function () {
        var self = this;
        self.name = ko.observable().extend({ required: "Name is required" });
        self.contact = ko.observable();
        self.phone1 = ko.observable();
        self.email = ko.observable().extend({email: true});
        self.website = ko.observable().extend({required: "Website is required"});

        self.Errors = ko.validation.group(self);

         self.save = function () {
            if (self.isValid()) {
                alert("no error");
            }
            else {
                alert("error");
            }
            alert("save clicked ");
        };

        self.cancel = function() {
            alert("cancel clicked");
        };
    };

    ko.applyBindings(new CustVM());

isValid is true even though i have not entered any required elements.

You are not using

ko.validation.registerExtenders();

that's why you are having problem, you can check my this ARticle:-
