Update information without updating page with CakePHP 3

How do I update some information without updating the page, I'm working with CakePHP 3. Ex: I have 2 lists, one with all items and one with the favorite items. In the first list I have the option to favor each item (except this information in the bd). I wish I did not need to refresh the page to update this information in the second list. What is the right way to do this?
