javascript - Angular 1.5.4 $http progress event

Question

Now Angular 1.5.4 finally allows you to track progress event on $http provider but for some reason I keep getting the $rootScope as a response instead of an actual progress (I'm using it for uploads) information. Because of lack of examples I found some tests in the Angular repo and followed that but to no success.

restClientInstance.post = function (requestParams) {
    var postParams = {
        method: "POST",
        url: API_URL + requestParams.url,
        headers: requestParams.headers,
        data: requestParams.data,
        eventHandlers: {
            progress: function (c) {
                console.log(c);
            }
        },
        uploadEventHandlers: {
            progress: function (e) {
                console.log(e);
            }
        }
    };

    var promise = $http(postParams)
    $rootScope.$apply();
    return promise;
};

In both cases it consoles $rootScope rather than the lengthComputable

In AngularJS v1.5.7 works fine. If you have the chance I recommend upgrade!

...//formData = new FormData(); etc...
var postParams = {
    method: 'POST',
    url: yourURLWS,
    transformRequest: angular.identity,
    uploadEventHandlers: {
        progress: function (e) {
                  if (e.lengthComputable) {
                     $scope.progressBar = (e.loaded / e.total) * 100;
                     $scope.progressCounter = $scope.progressBar;
                  }
        }
    },
    data: formData,
    headers: {'Content-Type': undefined }
};

var sendPost = $http(postParams); //etc...

in HTML you have:

<progress id="progress" max="100" value="{{progressBar}}"></progress>{{progressCounter}}%

Result:

progress result
