Popup from multiple services

Question

I am trying to have one infowindow/popup show from multiple services. I have successfully added the second service to my code, however, only 1 result will display.

Ex. if I am at full scale, only the zoning layer is returned in the popup. If I zoom in, only the parcel layer is returned in the popup.

How can I get both services to show within the popup? Additionally, how can I make it so only the visible layers show within the popup?

Here is the code I have edited:

dojo.require("esri.dijit.Popup"); //Infowindow

var identifyTask,identifyParams;    

  function mapReady(map){

   dojo.connect(map,"onClick",executeIdentifyTask);

   //create identify tasks and setup parameters 
   identifyTaskZoning = new esri.tasks.IdentifyTask("https://www.marioncountyfl.org/arcgis/rest/services/Dynamic/Zoning/MapServer");
   identifyTaskParcels = new esri.tasks.IdentifyTask("https://www.marioncountyfl.org/arcgis/rest/services/Dynamic/Parcels/MapServer");

        //Set Zoning Parameters
   identifyParamsZoning = new esri.tasks.IdentifyParameters();
   identifyParamsZoning.tolerance = 7;
   identifyParamsZoning.returnGeometry = true;
   identifyParamsZoning.layerIds = [0,1,2,3,4];
   identifyParamsZoning.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_VISIBLE;
   identifyParamsZoning.width  = map.width;
   identifyParamsZoning.height = map.height;
        //Set Parcel Parameters
   identifyParamsParcels = new esri.tasks.IdentifyParameters();
   identifyParamsParcels.tolerance = 15;
   identifyParamsParcels.returnGeometry = true;
   identifyParamsParcels.layerIds = [0,1,2,3,4];
   identifyParamsParcels.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_VISIBLE;
   identifyParamsParcels.width  = map.width;
   identifyParamsParcels.height = map.height;

   //resize the map when the browser resizes
   dojo.connect(dijit.byId('map'), 'resize', map,map.resize);
  };

  function executeIdentifyTask(evt){
 identifyParamsParcels.geometry = evt.mapPoint;
 identifyParamsParcels.mapExtent = map.extent;
 var deferred = identifyTaskParcels.execute(identifyParamsParcels);
 deferred.addCallback(function(response){
   if (response.length > 0) {
//         console.log(response.length)
//         response is an array of identify result objects    
//         Let's return an array of features.
    return dojo.map(response, function(result){
      var feature = result.feature;
      feature.attributes.layerName = result.layerName;
      if(result.layerName === 'TaxParcel'){

Check out this blog entry I wrote about identifying multiple services with dojo DeferredList. It address only the visible layers. Once you have the result, you'll have to create a custom popup. http://www.spatialexception.org/posts/arcgis-javascript-identifytask-returns-scale-dependent-layers

Edit
I'm using jqueryUI to create widgets so I'm not sure if you want to use this, but here's the way I'm displaying. It's not really a popup, but more like an ArcMap Identify. The code needs to be cleaned up, e.g. get the html out of the javascript, but here it is...
