Change these line in IndexController.php

$model = Mage::getModel("vendorcomplaints/complaints")
                    ->addData($post_data)
                    ->setId($this->getRequest()->getParam("id"))
                    ->save();

To

$id = $this->getRequest()->getParam("id");
$model = Mage::getModel("vendorcomplaints/complaints")->load($id)->addData($post_data);
$model->setId($id)->save();

Because you need to load the table row id before updating the data.
