OnError and OnSuccess - parameter

[adalbertpl]

In documentation in configuration section we have information about onError and onSuccess function which should receive image paramater. But I cannot find description of the parameter in documentation.

  angular.module('your.module', [
    'angularLazyImg'
  ]).config(['lazyImgConfigProvider', function(lazyImgConfigProvider){
    var scrollable = document.querySelector('#scrollable');
    lazyImgConfigProvider.setOptions({
      offset: 100, // how early you want to load image (default = 100)
      errorClass: 'error', // in case of loading image failure what class should be added (default = null)
      successClass: 'success', // in case of loading image success what class should be added (default = null)
      onError: function(image){}, // function fired on loading error
      onSuccess: function(image){}, // function fired on loading success
      container: angular.element(scrollable) // if scrollable container is not $window then provide it here
    });
  }])

I found that the image parameter doesn't contain any information about an angular scope. I probably cannot get information about DOM element too.
I found additionally that I must myself run $scope.apply() to get information about class change. I attach to events with $rootScope.on('lazyImg:error') and $rootScope.on('lazyImg:success'), in which functions I run $scope.apply().
