Featured Image not loading with ajax

I have edited td_module_9 replacing the line:

echo $this->get_image('art-big-1col');

with:

if (has_post_thumbnail()) {
echo $this->get_image('art-big-1col');
} else {
get_the_image(array('order' => array('meta_key', 'scan', 'default'), 'meta_key' => 'featured_image', 'scan' => true, 'default' => 'default-img-326.jpg', 'image_class' => 'entry-thumb')); ?>
}

get_the_image function grabs an image from a custom field, if there is no image scans the post for images to get the first one and finally if post doesn’t contain images uses a default one.

This code works fine but when I insert module 9 inside a page with Visual Composer choosing ajax pagination, the featured images appear on the first page only but are not shown up when ajax tries to fetch them for next pages.

Is there anything I can do about that?

Thanks a lot.
