@valera-rozuvan you can use:
```javascript
this.videoCaption.subtitlesEl
    .on('scroll', this.videoCaption.autoShowCaptions)
    .on('scroll', this.videoControl.showControls);
```
**or**

```javascript

this.videoCaption.subtitlesEl
    .on({
        'scroll': function (event) {
            this.videoCaption.autoShowCaptions(event);
            this.videoControl.showControls(event);
        }
    });
```
