Magento – Custom module form data is not saving in magento

I am new to magento, I have created custom module which is contactpro. in this I am getting data and receiving mail and redirecting page also, but data is not saving in my table.

my code is:

IndexController.php

public function postAction(){

        $session            = Mage::getSingleton('core/session');
        $data               = Mage::app()->getRequest()->getPost();
        $this->_data        = $data;

        $validate = $this->validate();

        if($validate === true){
            $session->addSuccess($this->__('Contact has been accepted for moderation.'));

                try {
                    $postData = $this->getRequest()->getPost();
                    Mage::log($postData);
                    Mage::log('================================');
                    $testModel = Mage::getModel('contactpro/contactpro');
                    Mage::log($testModel);
                    $testModel->setCreatedTime(Mage::getSingleton('core/date')->gmtDate());
                    $testModel->addData($postData)->setUpdateTime(Mage::getSingleton('core/date')->gmtDate())
                        ->setId($this->getRequest()->getParam('contact_pro_id'))
                        ->save();
                    Mage::getSingleton('adminhtml/session')->addSuccess('successfully saved');
                    Mage::getSingleton('adminhtml/session')->settestData(false);
                } catch (Exception $e){
                    Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
                    Mage::getSingleton('adminhtml/session')->settestData($this->getRequest()->getPost());
                }

            //$this->sendEmail();
            $pageThanks = Mage::getStoreConfig('contactpro/settings/page_thanks',$this->_getStore());
            $this->_redirect($pageThanks);
        }else{
            if (is_array($validate)) {
                foreach ($validate as $errorMessage) {
                    $session->addError($errorMessage);
                }
            } else {
                $session->addError($this->__('Unable to post the contact.'));
            }
            $this->_redirect('contactpro');
        }
    }

and I have receive system.log file

$installer = $this;

$installer->startSetup();

$installer->run("

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

    ");

$installer->endSetup(); 

magento\app\code\local\Easylife\Contactpro\Model\Contactpro.php

 <?php

    class Easylife_Contactpro_Model_Contactpro extends Mage_Core_Model_Abstract
    {
        public function _construct()
        {
            parent::_construct();
            $this->_init('Contactpro/Contactpro');
        }
    }

magento\app\code\local\Easylife\Contactpro\Model\Resource\Contactpro.php

<?php

class Easylife_Contactpro_Model_Resource_Contactpro extends Mage_Core_Model_Resource_Db_Abstract
{
    public function _construct()
    {
        $this->_init('contactpro/contactpro','contactpro_pro_id');
    }

}

magento\app\code\local\Easylife\Contactpro\Model\Resource\Contactpro\Contactpro.php

<?php

class Easylife_Contactpro_Model_Resource_Contactpro_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract
{



    protected $_intervals = null;

    public function _construct()
    {
        $this->_init('contactpro/contactpro');
    }


    public function getIntervals()
    {
        if (!is_null($this->_intervals)) {
            return $this->_intervals;
        }

        return 1;
    }

}

can any one tell me where I went wrong?
