valuechangeListener not working-inputNumberSpinner

[abcd1]

hii everyone

the valueChangeListener is not working for inputNumberSpinner
nothing is happening when i press the submit button

my code is

<h:form>
<rich:inputNumberSlider value="500" width="300" maxValue="1000"
step="50" showToolTip="false" id="islider" valueChangeListener="#{inputnumberSlider.valueChangeListener}">
</rich:inputNumberSlider>
<a4j:commandButton value="Submit"/>
</h:form>

bean is

public void valueChListener(ValueChangeEvent event) {
 valueChangeListener = (String) event.getNewValue();
}

public String getValueChangeListener() {
 return valueChangeListener;
}

have any idea
thanks in advance
cheers

<rich:inputNumberSpinner valueChangeListener="#{bean.listener}"/>
 <rich:inputNumberSlider valueChangeListener="#{bean.listener}"/>

 <h:commandButton value="submit"/>
 <a4j:commandButton value="ajax submit"/>

public void listener(ValueChangeEvent event) {
 System.out.println(event.getSource());
 }

Both listener called fine for me from both buttons and I can see in log:
