Problemas na injeção do Bean | Java EE parte 1: crie sua loja online com CDI, JSF, JPA

Acredito que seja um erro básico, mas sempre que dou o submit, dá erro de target unreachable, é como se o CDI não estivesse injetando o bean.

Exception:

javax.servlet.ServletException: /livros/form2.xhtml @12,59 value="#{livrosBean.livro.titulo}": Target Unreachable, identifier 'livrosBean' resolved to null

Esse é o bean

package ao.com.casadocodigo.beans;

import java.io.Serializable;

import javax.enterprise.context.RequestScoped;
import javax.inject.Named;

import ao.com.casadocodigo.entities.Livro;

@Named
@RequestScoped
public class LivrosBean implements Serializable{
    private static final long serialVersionUID = 1L;

    private Livro livro = new Livro();

    public void salvar() {
        System.out.println("Salvou");
    }

    /**
     * @return the livro
     */
    public Livro getLivro() {
        return livro;
    }

    /**
     * @param livro the livro to set
     */
    public void setLivro(Livro livro) {
        this.livro = livro;
    }
}

Esse é o form:

Está tudo de acordo com o curso e como o forge gera os artefatos. Gostaria de um auxílio.
