AngularJS: File upload with angular js event ng-change not working

When we are working with angular js and want to upload file using angular js event then we need to use ng-change event for accessing file upload method. But in some cases ng-change event doesn't work for file upload.
Then we need to use onchange event of that html control like

  
 onchange="angular.element(this).scope().UploadFileFromButton(this)"

with the help of above code you can call angular js event at the time file upload.

UI

Angular JS function

$scope.UploadFileFromButton = function (obj) {
        $($(obj)[0]).off('ajax', function () { });
        if ($scope.chkFileTypes($(obj)[0].files)) {
            $scope.UploadDataFile(1); // call file upload method
            prgSingleUpload.value = prgSingleUpload.innerHTML = 100;

            prgUpload.value = (prgUpload.value) + (100 / number);
            GlobalFileIndex--;

            if (GlobalFileIndex == 0) {
                imgCompleted.style.display = 'inline-block';
            }

            divUploadCount.innerHTML = "Overall Files Uploaded :- " + (number - GlobalFileIndex) + " / " + number;
        }
