Android PagedList updates

My question is how to update item in PagedList?

In my case, there are ListActivity and DetailsActivity. List activity is using Paging component to get posts from network(only) and shows it in recycler view using paged adapter. When user is pressing on some post, I need to get post details and show it at the DetailsActivity. I am making another request to the server and it returns me post details. After that call, server increases viewsCount value of that post and when user returns to the posts list, I need to update that counter at the list item.

The question is, how to update single item (post), in that PagedList, cause I don't need to reload all list from the beginning just to update one single item.
