Dropdown's valueChangeListener not working with primefaces datatable

I have datatable and a dropdown within a xhtml. If I am deleting p:datatable code within this page then I am able to call the valueChangeListener of dropdown , but if p:datatable is present in xhtml, then I am not able to call it.

Xhtml code is

<ui:define name="content">
    <f:view>
        <h:form id="accountSummaryForm" prependId="false">
            <h:selectBooleanCheckbox id="checkbox" value="true" />
            <h:outputLabel value="Show certificates preview on sumit"></h:outputLabel>
            <h:outputLabel value="Show certificates preview on sumit"></h:outputLabel>
            <h:outputText align="left"
                value="Value is #{reqSummaryHandler.certNumber}" />
            <p:dataTable id="reqActList" paginatorAlwaysVisible="true"
                var="reqInfo" value="#{reqSummaryHandler.certActListModel}"

                <f:selectItem itemLabel="Issue  Distribute" itemValue="A" />
                <f:selectItem itemLabel="Send to Underwriter" itemValue="B" />
                <f:selectItem itemLabel="Issue  Do Not Distribute" itemValue="C" />
            </h:selectOneMenu>
        </h:form>
    </f:view>
</ui:define>

And listener code is

    public void DoPathProcessing1(ValueChangeEvent event) {
    String newValue = (String) event.getNewValue();
    System.out.println("Path"
            + certActListModel.getRowData().getRoutePathCd());
    certActListModel.getRowData().setRoutePathCd(newValue);

    System.out.println("value is " + newValue);
}

Any idea why it is not working?

I am using jsf-api-2.0.3 and primefaces-2.2.1

You are using both the value and the valueChangeListener attributes of the drop down component. Why would you do this?

Just having value="#{reqSummaryHandler.certNumber} will call setCertNumber(String certNumber) in your managed bean. Why not just put this code into the setter method?
