Sorting posts dynamically


I am trying to add a sort dropdown on my tags and author pages. The idea is that a user should be able to sort the list of articles alphabetically, or chronologically, or by some other order available. And I want to do this without having to reload the entire page.

Can someone help me with how this can be done using handlebars? I just want to rerender the section with the list of posts based on what the user chooses from the sort dropdown. An implementation on the default Casper theme would be great for reference.

Thanks in advance!
