update primefaces dataTable with new rows adding dynamically

Question

When I click on the button New , a new row is added to my dataTable on only the first click and the page is refreshed. Several cliques except the first were not refreshes the dataTable. So to see my newly added rows, I use the F5 key to refresh my page. Certainly my update="dataTableSaisiePiece" not work or only works rather the first click.

Here is my page home.xhtml :

My ManagedBean:

    @ManagedBean (name = "ecritureCtrl")
    @SessionScoped
    public class EcritureCtrl {
    private List lignes = new ArrayList();
    Avant unUser;

    private String description;
    private Date date;
    private String code;
        public EcritureCtrl() {
            lignes.add(new Avant());
         }

        public void newLine(ActionEvent actionEvent){
            lignes.add(new Avant());            
        }

    }

Could you please help me ? Thanks in advance.

this seems to work for me

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.event.ActionEvent;

@ManagedBean
@SessionScoped
public class EcritureCtrl implements Serializable {
    private static final long   serialVersionUID    = 1L;
    private String              code;
    private Date                date;

    private String              description;
    private List         lignes              = new ArrayList();
    private Avant               unUser;

    public String getCode() {
        return this.code;
    }

    public Date getDate() {
        return this.date;
    }

    public String getDescription() {
        return this.description;
    }

    public List getLignes() {
        return this.lignes;
    }

    public Avant getUnUser() {
        return this.unUser;
    }

    @PostConstruct
    private void init(){
        this.lignes.add(new Avant());
    }

    public void newLine(ActionEvent actionEvent) {
        this.lignes.add(new Avant());
    }

    public void setCode(String code) {
        this.code = code;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public void setLignes(List lignes) {
        this.lignes = lignes;
    }

    public void setUnUser(Avant unUser) {
        this.unUser = unUser;
    }

}

and
