How to add ValueChangeListener Programmatically

Using an EL String, we can add ValueChangeListener in Oracle ADF using the below code:

private static MethodBinding getValueChangeListener(String el) {
        Class[] parms = new Class[] { ValueChangeEvent.class };
        MethodBinding mb =
            FacesContext.getCurrentInstance().getApplication().createMethodBinding(el,
                                                                                   parms);
        return mb;
    }

pass the EL Expression to the util method

ui.setValueChangeListener(getValueChangeListener("#{pageFlowScope.demoBean.valueChangeListener}"));
