Как изменить стандартную валидацию HTML5

[pekinessik]

Привет ВСЕМ, возник такой вопросик: Как изменить стандартную валидацию HTML5 для поля

{{ form_widget(form_main_search.searchString,  {'attr': {'class': 'ads-title-widget'}}) }}

плагины Jquery не прокатывают.

<form action="{{ path('OmlookSearchBundle_setDealSearchParameters') }}" method="post" {{ form_enctype(form_main_search) }} id="contactForm">    
    <div class="span7 search-logo">
           <ul class="clearfix">
               <li class="search-google span"><a  id="search-link-first" target="_blank" href="http://www.google.com" title="{%trans%}CB_BUTTON_SEARCH_GOOGLE{%endtrans%}"><img  src="{{ asset('omlook/img/search/google.png') }}" alt="img_google"></a></li>
               <li class="search-yandex span"><a  target="_blank" href="http://www.yandex.ru" title="{%trans%}CB_BUTTON_SEARCH_YANDEX{%endtrans%}"><img  src="{{ asset('omlook/img/search/yandex.png') }}" alt="img_yandex"></a></li>
               <li class="search-mail span"><a  target="_blank" href="http://go.mail.ru" title="{%trans%}CB_BUTTON_SEARCH_MAILRU{%endtrans%}"><img  src="{{ asset('omlook/img/search/mail_ru.png') }}" alt="img_mail"></a></li>

          </ul>
     </div>
<div class="search-all">
  <div class="search span" >
  {{ form_widget(form_main_search.searchString,  {'attr': {'class': 'ads-title-widget'}}) }} 
  {{ form_widget(form_main_search._token, {'attr': {'class': 'text validation noempty', 'id': 'title'}}) }}
  </div>
  <div class="search span">
        <button type="submit" name="login" title="" class="btn btn-info btn-large span" style=""><i class="icon-search icon-white"></i> &nbsp;{%trans%}UB_BUTTON_LOOK{%endtrans%}</button>    
  </div>      
</div>
<div class="new-used span7">
    <div class="pull-left">        
        {{ form_widget(form_main_search.dealProductState,  {'attr': {'class': 'span3'}}) }}     
    </div>
    <a href="{{ path('OmlookSearchBundle_search')}}" class="advanced-search pull-right" title="">{%trans%}UB_BUTTON_ADVANCED_SEARCH{%endtrans%}</a>
</div>
</form>

Спасибо.
