Batch replace smart objects with displacement map

Hi there, i am using this script for replace smart object with images.

Problem is that on the layer in which I need to change the image imposed displacement map, and each time a window pops up asking to update the displacement map.

How to add a change of the displacement map in the script?

#target photoshop

if (app.documents.length > 0) {

var myDocument = app.activeDocument;

var theName= myDocument.name.match(/(.*)\.[^\.]+$/)[1];

var thePath = myDocument.path;

var theLayer = myDocument.activeLayer;

// jpg options;

var jpgopts = new JPEGSaveOptions();

jpgopts.embedProfile = true;

jpgopts.formatOptions = FormatOptions.STANDARDBASELINE;

jpgopts.matte = MatteType.NONE;

jpgopts.quality = 8;

// check if layer is smart object;

if (theLayer.kind != "LayerKind.SMARTOBJECT") {alert ("selected layer is not a smart object")}

else {

// select files;

if ($.os.search(/windows/i) != -1) {var theFiles = File.openDialog ("please select files", "*.psd;*.tif;*.jpg", true)}

else {var theFiles = File.openDialog ("please select files", getFiles, true)};

if (theFiles) {

// work through the array;

          for (var m = 0; m < theFiles.length; m++) {

// replace smart object;

                    theLayer = replaceContents (theFiles[m], theLayer);

                    var theNewName = theFiles[m].name.match(/(.*)\.[^\.]+$/)[1];

//save jpg;

                    myDocument.saveAs((new File(thePath+"/"+theName+"_"+theNewName+".jpg")),jpgopts,true);

                    }

          }

}

};

////// get psds, tifs and jpgs from files //////

function getFiles (theFile) {

     if (theFile.name.match(/\.(psd|tif)$/i) != null || theFile.constructor.name == "Folder") {

          return true

          };

     };

////// replace contents //////

function replaceContents (newFile, theSO) {

app.activeDocument.activeLayer = theSO;

// =======================================================

var idplacedLayerReplaceContents = stringIDToTypeID( "placedLayerReplaceContents" );

    var desc3 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

    desc3.putPath( idnull, new File( newFile ) );

    var idPgNm = charIDToTypeID( "PgNm" );
