Model Property Changed

Listening for model property changes can be done via propertyChanged on adEvents and mediaEvents.

How To

To listen for when the media volume has changed:

var MediaEngineModelProperty = TOP.models.MediaEngineModelProperty;

player.model().mediaEvents().propertyChanged.listen(function(result)
{
    switch (result.property)
    {
        case MediaEngineModelProperty.Volume:
            console.log('[propertyChanged]\n\tproperty:', result.property, '\n\told:', result.oldValue, '\n\tnew:', result.currentValue);
            break;
    }
});

player.setVolume(0.25);

Shows this in the console:

[propertyChanged]
  property: (2) ["Volume", 3, toString: ƒ, __enum__: {…}] 
  old: 1 
  new: 0.25

Some property change events are already being dispatched through the PlayerApiEvents. For the volume model property changed example, the player has adVolumeChanged and mediaVolumeChange events.
