angularjs with soundmanager, update DOM on whileloading

I'm new to Angularjs, and I'm trying to create a simple player using soundManager library.

The problem i'm facing is about updating the DOM, during sound loading/playing.

The soundManager Sound object exposes some dynamic properties like bytesLoaded or position and I'm trying to figure out how to bind them to the DOM.

I tried with something like

<span ng-bind="sound.bytesLoaded"></span>

where sound is an instance of the sound object attached to the root $scope, but it seems the DOM is updated only once in this way.

The problem might be that the sound.bytesLoaded is updated in non-angular world like, callback function of bytes loaded or some similar callback methods which is non-angular world.

To make the view update while updating the model value in non-angular world, you may need to call the $scope.$apply method from within the callback method of the SM2.

Some pseudo code:

sound.on('bytesLoaded', function(bytesLoaded){
  // Imagine you have some similar kind of the callback in SM2,
  // where you will be updating the sound.bytestLoaded property.
  sound.bytesLoaded = bytesLoaded;
  $scope.$apply(); // please make sure you call have this line
                   // where you are updating the bytesLoaded property. 

})
