I have a function in my component class where I attach scroll event listener. I am doing this:

```
private _scrollListener(event){
    console.log("inside the scroll listener; this: ",this);
    this._zone.run(() => {
        this.checkForLazyLoad = !this.checkForLazyLoad;
    })
}

ngOnInit() {
    window.addEventListener("scroll", this._scrollListener);
}

```

Problem is that the value of "this" keyword in the private function "\_scrollListener" points to window object. How would I get the value of my class' instance inside scroll event listener?
