event doesn't fire in ValueChangeEvent of

Question

The problem is in my content part of the template. ValueChangeEvent of content pages cannot fire anymore when i set them in tag. I cannot get the value of selected item in SelectOneMenu even though i am using omnifaces converter because could not reach the CityChaged event.This problem doesn't occur when i tried without using template and also can get value to persist. Please give me some advice, i got similar errors by using template.Thanks.

This is my template page.

This is my content page.

 




    
        
            

                
                

                    
                    
                    

                    
                        #{pg.cityID}
                       

                    
                        #{pg.cityName}

This is my backing bean.

@ManagedBean(name = "ManageDeliveryCharges")
@RequestScoped
public class ManageDeliveryCharges{

    private City city;
    private List citySelectedItems = null;
    private City selectedCity;
    private List cityList;

    @ManagedProperty("#{TownshipService}")
    private ITownshipService townshipService;


    @PostConstruct
    public void Page_Load(){
        prepareForAdd();

        cityList = cityService.findAllCity();
        citySelectedItems =new ArrayList();

        for(City city:cityList){
            SelectItem item =new SelectItem(city,city.getCityName());
            citySelectedItems.add(item);
        }
    }


    public void CityChanged(ValueChangeEvent ex){
        System.out.println("City ID is " + selectedCity.getCityID() + "City Name is " + selectedCity.getCityName());
        deliveryCharges.setCity((City)((UIOutput) ex.getSource()).getValue());


    }   

    public List getCitySelectedItems() {
        return citySelectedItems;
    }

    public void setCitySelectedItems(List citySelectedItems) {
        this.citySelectedItems = citySelectedItems;
    }

    public List getCityList() {
        return cityList;
    }

    public void setCityList(List cityList) {
        this.cityList = cityList;
    }

    public void setCityService(ICityService cityService) {
        this.cityService = cityService;
    }

    public IDeliveryChargesService getDeliveryChargesService() {
        return deliveryChargesService;
    }

    public City getCity() {
        return city;
    }

    public void setCity(City city) {
        this.city = city;
    }


}

Update1. CityChanged method is actually like this.

public void CityChanged(AjaxBehaviorEvent ex){
        System.out.println("City ID is " + selectedCity.getCityID() +     "City Name is " + selectedCity.getCityName());
        deliveryCharges.setCity((City)((UIOutput)    ex.getSource()).getValue());

You must use the events which is provided by p:commandButton component. For more details primefaces-p Tag selectOneMenu

p:commandButton having only one event i.e is onchange. Replace with below line.

For example p:inputText supports events like onblur, onchange, onclick, ondblclick, onfocus, onkeydown, onkeypress, onkeyup, onmousedown, onmousemove, onmouseout, onmouseover, onmouseup, onselect use these events in p:ajax component of event attribute.

The event names start with on then click on ctrl + space displays supported events.
