Product Combo and play value in inputText

I am developing a DOCUMENT registry with parameters like Material, Name and other data. And as it will work, I make a normal PRODUCT registration with Material and Name parameters and in the registration screen of the DOCUMENT I want to open a combo like this "Material" code and choosing it, the name will be automatically played in the inputText field of NAME.

I created the combo and I can select it.

How to accomplish this function, something from JSF, JavaScript? I was told of the valueChanceListener, but tmb I do not know what it would be like?

Screen:

::PRODUCTEntity

@Audited@Entity@Table(name="produto")
public class Produto implements Serializable{

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@Column(name = "material", unique = true, length = 5, nullable = false)
private int material;

@IdentificaCampoPesquisa(descricaoCampo = "Nome", campoConsulta = "nome",      principal = 1)
@Column(name = "nome", nullable = false, length = 50)
private String nome;

:: Entity DOCUMENT

@Audited
@Entity
@Table(name = "documento")
public class Documento implements Serializable{

private static final long serialVersionUID = 1L;

@IdentificaCampoPesquisa(descricaoCampo = "Código", campoConsulta = "id")
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@Column(name = "material", length = 5, nullable = false)
private int material;

@IdentificaCampoPesquisa(descricaoCampo = "Nome", campoConsulta = "nome",      principal = 1)
@Column(name = "nome", nullable = false, length = 50)
private String nome;

:: SCREEN AND SELECTONEMENU
