I'm starting with EJB. I can insert and list from a database but I can not delete records.

My entity:
Code:
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity	
public class Client {
	
	@Id	
	@GeneratedValue(strategy=GenerationType.IDENTITY)	
	private Integer id;
	
	@Column
	private String name;

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
	
}
My ManagedBean:
Code:
import java.util.ArrayList;
import java.util.List;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.naming.InitialContext;
import javax.naming.NamingException;


@ManagedBean
@ViewScoped
public class ClienteMB {

	private Client client = new Client();
	private List<Client> lstClient =  new ArrayList<Client>();
	
	public String includeClient(){
		InitialContext ini;
		try {
			ini = new InitialContext();
		
			ClientBean clientBean = (ClientBean)ini.lookup("java:module/ClientBean");
			
			clientBean.save(client);
			client = new Client();
			lstClient = clientBean.searchClient();
			
		} catch (NamingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		return null;
	}
	
	public String deleteClient(){
		InitialContext ini;
		
		try {
			ini = new InitialContext();
			
			ClientBean clientBean = (ClientBean)ini.lookup("java:module/ClientBean");
			clientBean.delete(client);
			
			client = new Client();
			lstClient = clientBean.searchClient();
		} catch (NamingException e) {
			e.printStackTrace();
		}
		
		return null;
	}

	public Cliente getClient() {
		return client;
	}

	public void setClient(Client client) {
		this.client = client;
	}

	public List<Client> getLstClient() {
		return lstClient;
	}

	public void setLstClient(List<Client> lstClient) {
		this.lstClient = lstClient;
	}
	
}
My EJB:
Code:
import java.util.List;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;


@Stateless
public class ClientBean {
	
	@PersistenceContext
	EntityManager em;
	
	public void save(Client client) {
		em.persist(client);
	}
	
	public void delete(Client client) {
		em.remove(client);
	}
	
	public List<Client> searchClient(){
		return em.createQuery("FROM Client").getResultList();
	}
}
My xhtml page:

      		<h:commandButton value="Save" action="#{clientMB.includeClient()}" />

      		<h:column>

      		<h:column>
      			<h:commandButton value="Delete" 
                                action="#{clientMB.deleteClient()}" />
      		</h:column>
      	</h:dataTable>
      
      </h:body>
</html>
The delete button does not give error but does not delete from the database. Why?
