Fill two other fields of a formset depending on autocomplete selection

Question

I would like to fill two other fields automatically depending upon the selection someone makes in an autocomplete field, using django-autocomplete-light. However, my java script is not that good, so I don't really know where to start. Any help is very much appreciated.

User submit their publicized papers. There is a "person" autocomplete field in a formset (its a many to many relation for authors and other people that worked towards the publication). If a user chooses a person, I want that persons name and family name automatically filled in two other fields in that formset, so that users can make changes (also, it is a prerequisite from the data modell). Same if they change or delete the selected person.

I thought best would be to have a view for name and a view for family name in order to retrieve those two with the id I could get from the autocomplete field.

However, how do I do the asynchronous retrieval of the names and fill them into the two fields?

Thank you!

there is something called forward attribute that you can mention in your form field in autocomplete light with that you can load values for your two fields but i still don't know how to make them selected
