jquery validation only validates first field - others are ignored

Question

I'm using a jQuery validation plugin which should validate all the inputs in a form, but it stops at the first one. If you click on the second input and leave it blank - everything is ok - it validates...
Otherwise - not...

I found some of the same answers - no success...

Here's my fiddle with the example I wrote

    $('.validate').validate({
        highlight: function(element) {
            $(element).parent().removeClass('has-success').addClass('has-error');
        },
        success: function(element) {
            element.closest().removeClass('has-error').addClass('has-success');
        }
  });

}); // end document.ready`enter code here`

Use name for the fields instead of id

<div class="form-group">
    <label class="control-label" for="login_id">Login id:</label>
    <input type="text" class="form-control required" name="login_id">
</div>
<div class="form-group">
    <label class="control-label" for="password">Password:</label>
    <input type="password" class="form-control required" name="password">
    <div class="forgot"> <a href="#">
                    Forgot your password?
                </a>

    </div>
</div>
