如何在Yii中使用图像进行ajax请求

I'am trying to make AJAX request and response with images in Yii and I don't know even where to start. I managed to display images from images folder using db requests for file names. I want to make it so when I click on one image it sends requests to the server and it updates my div with another pictures with comes out from db.

What I got is Controller:

$modelCars = EeCarTypes::model()->findAll();
        $this->render('index',array(
            'model'=>$modelCars,
        ));

And view:

$uploadUrl = Yii::app()->request->getBaseUrl(true) . '/images/upload/cartypes/';

foreach( $model as $key => $item )
{
    $imgName = $model[$key]->attributes['car_type'];
    $imgID = $model[$key]->attributes['id'];
    $imgFullUrl = $uploadUrl . $imgName;
    echo "<a href=\"$imgID\"><img src=\"$imgFullUrl\" alt=\"$imgName\"></a>";
}

I tried to find some widget that would do it for me but I coudnt find one. I would appriciate some tips, links, ideas. Thanks you guys a lot.

Index view:

    <script>
    $('.image').click(function (e) {
        $.ajax({
            dataType: "html",
            data: {primaryKey: "keyImage"}
            success: function (data) {
                $('#imageContainer').html(data);
            }
        }); 
    });
</script>

Controller:

 function actionIndex()
    {
        if (Yii::app()->request->isAjaxRequest && Yii::app()->request->getQuery('primaryKey')) {
            $model = EeCarTypes::model()->findByPk($_GET['primaryKey']);
            echo $this->renderPartial('/view/..', ['model' => $model]);
            Yii::app()->end();

        }
        $this->render('index');
    }

View for renderPartial: get $model and print image
