Adding validation with MVC 3 & jQuery Validator in execution time

Question

I have a form with validation rendered by c# when the page is loaded, the rendered fields like so:

Answer 1

I solved here using

jQuery.validator.unobtrusive.parseElement($("#element")[0], false);
$.validator.unobtrusive.parseDynamicContent($("#element")[0]);

parseDynamicContent I got here

Answer 2

Feels like a bit of a hack, but here's how I've done it.

// Target Form
var $form = $("**form selector**");

// Unbind existing validation
$form.unbind();
$form.data("validator", null);

// Check document for changes
$.validator.unobtrusive.parse(document);

// Re add validation with changes
$form.validate($form.data("unobtrusiveValidation").options);
