Error validating a laravel modal form using AJAX

I am trying to validate a modal form using ajax. I want the error to show on the modal instead of the modal closing. But this does not work

I am using this repo- http://ift.tt/2nxkljp

This is my view

<div class="modal fade" id="" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
   <div class="modal-content">
     <form action = "" method="post" class="bootstrap-modal-form">  
        <div class="modal-body">
            <input type="text" name="name">
        </div>
        <div class="modal-footer">
          <a class="btn btn-default btn-ok" data-dismiss="modal">Cancel</a>
         <input type="submit" value="submit"  class="btn btn-danger">
       </div>
  </form>
 </div>

 @section('script')
       <script type="text/javascript">
         $(document).ready(function() {
          // Prepare reset.

        function resetModalFormErrors() {
           $('.form-group').removeClass('has-error');
             $('.form-group').find('.help-block').remove();
        }
    // Intercept submit.
     $('form.bootstrap-modal-form').on('submit', function(event) {

          var form   = $(this),

          submit = form.find('[type=submit]');

          // Check for file inputs.
         if (form.find('[type=file]').length) {
          // If found, prepare submission via FormData object.
             var input       = form.serializeArray(),

This is my controller

 public function send_rfq(Request $request){
        $validator = Validator::make($request->all(), [
            'name' =>'required'
        ]);
        if($validator->fails()){
            return back()
                ->withErrors($validator)
                ->withInput();
        }
    }
