get active tab id(collibsable) inside a accordionPanel using jquery in primefaces

Question

Objective: I need to check that is there any change in the field of form which is inside a tab.

Approach: I will call a Jquery method on value change of input field and update the value of hidden field inside a perticular collipsable.

Challenge: I am facing a challenge in getting the id of that hidden field and the id of collipsable in which form change is occurring.

sample code:

XHTML

<p:accordionPanel id="FacilityAccordId" activeIndex="null"
        dynamic="true">
        <p:ajax event="tabChange" listener="#{facilities.saveClicked}" />
        <p:tab id="priortabId" title="Prior Sanction/Review Info">
                <p:panel id="priorPanelId" header="Prior Sanction/Review Info">
                <h:inputHidden id="reviewHidden" value="#{facilities.hiddenReview}"></h:inputHidden>

<p:inputText value="#{facilities.sanctAuth }" styleClass="textbox" id="psrSanctAID"  />
                                    <label><h:outputText value="Sanction Authority" /> </label>
</p:panel>


        </p:tab>

</p:accordionPanel>

JQUERY:

$(document).ready(function() {
  // alert('mkm');
   jQuery(document.body).on('change', 'input', function(event) {
      // alert('chnage called12');
       //var active = $('.selector').accordion('option', 'active');
      // alert("value::::"+active);
       var data=$('#reviewHidden').val();
       $('#reviewHidden').val('true');
    });
});

Please help in achieving the objective also suggest if any approach you are having for auto save in Primefaces.
