How to make youtube player to stop on a particular time?

I'm trying

``` javascript
$scope.youtubePlayer.seekTo(Number(part.start));
$scope.youtubePlayer.playVideo();
$scope.playerVars.end = Math.ceil(Number(part.end));
```

While my markup is:

``` html

```

So when the three lines of JS are triggered, video starts to play at proper second but it won't stop. It's true that at first `$scope.playerVars` equals to an empty object, but I think it should work that way.

I also tried a $watch on `getCurrentTime()` but didn't work.

Start with the youtube-video markup and the calls to seekTo(), playVideo(), playerVars.end, and getCurrentTime() shown in the issue. Reproduce the playback flow and determine why the player does not stop at the requested end time; done means playback reliably stops at that time.
