Cordova FileTransfer Addon - Refreshes Back To App Root

I’m creating an Ionic App using the ngCordova FileTransfer plugin. I have it installed and setup. I have a click function in my view modeled to the function that should be downloading the file in my App. I am building my url and filename from data returned by a service.

When I tap the link, it pops open to a new “view” in the app which is the default state from my app.js file. I’m sure I’m missing something small. Can someone take a look at this and let me know if they see anything glaring?

  $scope.showProgress = false;
  $scope.downloadLink = function () {

    var index;
    var formLinks;
    for (index = 0; index < $scope.formularyLookupDetails.length; index++) {
      formLinks = $scope.formularyLookupDetails[index];

    var filename = formLinks.LinkUrl.split("/").pop();
    var targetPath = cordova.file.externalRootDirectory + filename;
    var options = {};
    var trustHosts = true;

    $, targetPath, options, trustHosts).then(function (result) {

    }, function (err) {

    }, function (progress) {
      $scope.showProgress = true;
      $timeout(function () {
        $scope.downloadProgress = (progress.loaded / * 100;
