custom event not working

[jitenderd]

I am using the angular version of golden layout (https://github.com/goldsam/ng-golden-layout) and faced one issue. I want to use ngui-scrollbar component inside one of the golden layout's panel.

npmjs link for ngui-scrollbar: https://www.npmjs.com/package/@ngui/scrollable
Example for ngui-scrollable on plunker : https://plnkr.co/edit/wLVudY?p=preview&open=app.component.ts

While integrating, I am facing problem in the execution of custom event "elementVisible" used on the html page. The event is working fine if we are integrating our component outside the golden-layout.

Any suggestions would help.
