Runtime Error: Object(...) is not a function

[omelsoft]

I found this directive helpful in one of my project by looking at each demo. However, when I tried to integrate this to my project I got an error which says Object(...) is not a function as you can see below.

Managed to fix this by updating the onScroll() method to return just the ionScroll.

onScroll(): Observable {
return this.content.ionScroll;
// return merge(this.content.ionScrollStart, this.content.ionScroll, this.content.ionScrollEnd);
}

Though you might want to take a look if this has other compatibility issues.
