folderTreeView.jstree(true)redraw(true)

folderTreeView = $(".folderpreview");
        // Files Treeview
        if (folderTreeView.length) {
          document.getElementById("preview").innerHTML = '<embed type="text/pdf" src=""  width="0" height="0" >';
          folderTreeView
            .on("changed.jstree", function (e, data) {
              //blabla
            })
            .jstree({
              core: {
                data: datanew.children,
              },
              plugins: ["types"],
              types: {
                default: {
                  icon: "far fa-folder font-medium-1",
                },
                ".jpg": {

I solved it by using
$(".folderpreview").jstree("destroy");
before updating the tree data
