How to setup a validator for a form from another model?

Question

Yii

I have one common Contact form, where 2 forms are taken from 2 models, full name from the Fio model, Number from the Phone model. For fio, I set up validation without problems with Phone, there were difficulties, it does not validate its field, requared shows but does nothing. How to setup Number validation in this view?
View Name

<?php
/* @var $this TownController */
/* @var $model Town */
/* @var $form CActiveForm */
?>

<div class="form">


    <?php $this->beginWidget(
        'booster.widgets.TbModal',
        array('id' => 'myModal')

    <?php $form = $this->beginWidget('booster.widgets.TbActiveForm', array(

Solved the problem with a third party validator using JavaScript and HTML5 validator bitsofco.de/realtime-form-validation. I got enough functionality.
