SelectOneListbox in an editable dataTable

Question

Hello,
I am trying to put a listBox in every row of an editable dataTable.
I am doing the following:
<h:form>
<h:dataTable binding="#{myRequestBean.dataTable}" value="#{myRequestBean.dataList}" var="dataItem">
<h:column>
<f:facet name="header">
<h:outputText value="ID" />
</f:facet>
<h:commandLink value="#{dataItem.id}" action="#{myRequestBean.editDataItem}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Comp ID" />
</f:facet>
<h:selectOneListbox binding="#{myLists.listbox}"/>
</h:column>
</h:form>
package mymodel;
import javax.faces.component.html.HtmlSelectOneListbox;
import java.util.Collection;
import java.util.ArrayList;
import javax.faces.model.SelectItem;
import javax.faces.component.UISelectItems;
public class MyLists
private HtmlSelectOneListbox listbox;
public HtmlSelectOneListbox getListbox() {
listbox = new HtmlSelectOneListbox();
Collection collection = new ArrayList();
collection.add(new SelectItem("11"));
collection.add(new SelectItem("22"));
collection.add(new SelectItem("33"));
UISelectItems listaMenu = new UISelectItems();
listaMenu.setValue(collection);
listbox.getChildren().add(listaMenu);
return listbox;
}I get the following exception: '#{myLists.listbox}' Target Unreachable, identifier 'myLists' resolved to null
What am I doing wrong?
Thank you
