If you want to validate the dynamically generated form using javascript:
You can use this code :

HTML :

<div id="example">
        <form id="newForm">
            <input type="text" name="email" id="email" value="mail" />
            <button type="submit">validate</button>
        </form>
    </div>
    <br/>
    <button id="newform">Create New Form</button>

Javascript :

var validateObj = {
             rules: {
                 email: {
                     email: true
                 }
             }
         };

         $(function () {

             jQuery.validator.setDefaults({
                 debug: true,
                 success: "valid"
             });

             // INITIALIZE plugin on the traditional form
             var validated = $('#newForm').validate(validateObj);

             $('#newform').one('click', function () {

                 var newform = '<form id="newForm2"><input type="text" name="email" id="email" value="bademail" /><button type="submit">validate</button></form>'
                 $('#example').append(newform);

                 // INITIALIZE plugin on the new form
                 var validate = $('#newForm2').validate(validateObj);
             });

         });

You have to include these two files also:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.13.1/jquery.validate.js"></script>

Hope this will help you!
