file in the controller says undefined - angularjs

Question

I am having trouble while uploading a file. I have created one service:
angular
.module('app')
.service('fileUpload', ['$http', function ($http) {
this.uploadFileToUrl = function(file, uploadUrl){
var fd = new FormData();
fd.append('file', file);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
})
.error(function(){
});
}}]);
then i have a directive:
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};}]);
And in the controller:
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' );
console.dir(file);
var uploadUrl = "/fileUpload";
fileUpload.uploadFileToUrl(file, uploadUrl);
};
HTML:
Browse <input type="file" file-model="myFile"/>
<button ng-click="uploadFile()">upload me</button>
As you can see i am using console.log in the controller and what i am having is
file is undefined
Thanks in advance!

change
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
scope: {
percent: "=fileModel"
},
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
scope.$watch('percent', function(value) {
console.log(value)
});
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};}]);
check the console value inside the percentage watch once you upload file
