Jquery dd/MM/yyyy date format validation

I using default ASP.NET MVC 4 validation bundle in my application. In view I have a date field in the format of "dd/MM/yyyy" and jquery validation failed to validate the format. Then I added the below code to override the default behavior.

$(function () {
        $.validator.methods.date = function (value, element) {
            Globalize.culture("en-GB");
            // you can alternatively pass the culture to parseDate instead of
            // setting the culture above, like so:
           // parseDate(value, null, "en-AU")
            return this.optional(element) || Globalize.parseDate(value) !== null;
        }
    });

Then the date validation issue was resolved, and now my application does not fire client side validation but the server side validation. what could be the reason for this behavior?
