“onchange” not working for selectOneMenu in PrimeFaces 3.2

My selectOneMenu isn't fireing an onchange event. Here is the code:

 <p:selectOneMenu id="select_preset" 
                  value="#{JobMgmtBean.presetGroupName}" 
                  valueChangeListener="#{PFJobMgmtBean.PresetGroupChangeEvent}" 
                  onchange="submit();">
    <f:selectItems value="#{JobMgmtBean.presetGroupList}"/>
</p:selectOneMenu>

The selectOneMenu is nicely populated, and I can select different values. But I would expect that after I change a selection, page would be refreshed, i.e. backing bean (RequestScoped) would be recreated (onchange="submit();")? But nothing happens when selection in the selectOneMenu is changed.

Also, value change listener PresetGroupChangeEvent() is not called.

Did I go wrong somewhere?

I'm using Tomcat 7.0.25 + MyFaces 2.1.6 + PrimeFaces 3.2.
