valueChangeListener on h:inputHidden not working

valueChangeListener on h:inputHidden not working

My XHTML:
<h:inputHidden id="json" value="#{indexManaged.json}"
valueChangeListener="#{indexManaged.goTo('datatable')}" />
My ManagedBean:
@ManagedBean
@ViewScoped
public class IndexManaged implements Serializable {
public String goTo(String page) {
Flash flash =
FacesContext.getCurrentInstance().getExternalContext().getFlash();
flash.put("json", json);
return page + "?faces-redirect=true";
}
}
Why isn't #{indexManaged.goTo('datatable')} getting fired?
