I am trying to add a functionality similar to adding an attachment to  
an email in Gmail.

I have a form to create object1. One field is to add a book  
reference. When you click the link “add book” a popup opens with the  
book form. Clicking the “add” button closes the popup and puts the  
title of the book in a text field associated with the book in  
object1’s form.

Now, I would like to add the functionality that another text field  
will appear with a link saying “add book” to open the popup again.  
How can I do that? I eventually also want to have the possibility of  
deleting the book reference.
