Looks like you completely missed the point of JSF and are rather new to web development. JSF is a server side language/framework which produces HTML code (rightclick page in browser and do View Source, do you see it now? no single JSF tag, it's one and all HTML). jQuery is a client side language which works with HTML DOM tree only. The is not a known HTML element. The browser don't have any idea how to deal with it. It only knows HTML like and friends.

You need to salvage the functional requirement in a "JSF-ish" way. Here's a kickoff example:

with

@ManagedBean
@ViewScoped
public class Bean implements Serializable {

    private List items;

    @PostConstruct
    public void init() {
        items = new ArrayList<>();
    }

    public void add() {
        Item item = new Item();
        item.setLabel("label" + items.size());
        items.add(item);
    }

    public void remove(Item item) {
        items.remove(item);
    }

    public List getItems() {
        return items;
    }

}

and

public class Item {

    private String label;
    private String value;

    // Let your IDE generate getters/setters/equals/hashCode.
}

That's all. No JavaScript mess necessary and everything is ready for save in server side by just adding another command button pointing to a save() method which passes the items variable further to the EJB/service/DAO class.

Otherwise, if you really want to do it the jQuery way, then you should drop JSF altogether and go for something request-based like Spring MVC. You only need to keep in mind that you've to write down all that HTML/CSS/JS yourself.
