globalajaxcompletehook.js

$.fn.activateAjaxForms = $.fn.activateAjaxForms || function () {
            return this.each(function () {
                var container = $(this);
                $('form.validated-form', container).each(function () {
                    var mode = $(this).data('validationMode');
                    $(this).validate({
                        ajax: mode == 'ajax',
                        continuationSuccess: function (continuation) {
                            continuation.form.trigger('validation:success', continuation);
                        }
                    });
                });
            });
        };
            $(document).ajaxComplete(function (data) {
                $(data).activateAjaxForms();
            });

Thought about this one more. With the latest changes in continuations and validation, here's my recommendation:
