I am trying to dynamically add Labels and textfields from Primefaces to my webpage. I want to use JQuery. Until now I realize the same task with Primefaces only and it works qui

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 <p:inputText> is not a known HTML element. The browser don't have any idea how to deal with it. It only knows HTML like <input> and friends.

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

<h:form>
    <ui:repeat value="#{bean.items}" var="item">
        <p:outputLabel for="foo" value="#{item.label}" />
        <p:inputText id="foo" value="#{item.value}" />
        <p:commandButton value="Remove" action="#{bean.remove(item)}" update="@form" />
        <br/>
    </ui:repeat>
    <p:commandButton value="Add" action="#{bean.add}" update="@form" />
</h:form>

with

@ManagedBean
@ViewScoped
public class Bean implements Serializable {

    private List<Item> 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<Item> 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.
