It's the parent `<ul>` that contains the items, but looking at that list of elements, it's a bit weird.  `.lb-item` is a lightbox link while `.lb-gallery` and `.lb-hidden-gallery` are the parent containers of lightbox links.  

I'm going to test with the following element list so that it's only binding the vclick/touchstart to lightbox links:

```javascript
elm.find('.lb-item, .lb-item-gal').on('vclick touchstart', function () {
```
