I am trying to use the “on-scroll” feature of “ion-content”. “on-scoll” is not working. ``` Page.html Page.ts private onPageScroll(): void { console.log("testing this"); } ``` I serve this to chrome. When i scroll the page, nothing happens. Nothing is printed to console. What am i doing wrong? Thanks ---

The current way to do it is like this: HTML: ```auto ``` JS: ```auto // Need to wait until the component has been initialized ngAfterViewInit() { // Here 'my-content' is the ID of my ion-content this.content = this.app.getComponent('my-content'); this.content.addScrollEventListener(this.onPageScroll); } onPageScroll() { console.log('They see me scrolling...'); } ``` Where did you see an `on-scroll` attribute? > **[Ionic Framework](https://ionicframework.com/docs/api/components/content/Content/)** > > Ionic is the app platform for web developers.

Thanks Brandy, i actually just saw that on the [Content](http://ionicframework.com/docs/v2/2.0.0-alpha.42/api/components/content/Content/)documentation. Implemented it already and came back here to give the answer. ---

@brandyshea, what is the datatype of the “this.content”? I’m using typescript, and I get an error: app.bundle.js:431 Uncaught (in promise) TypeError: this.content.addScrollEventListener is not a function(…) ---

Thanks for the hint @brandyshea. I have a problem detecting iOS momentum. I need to fire events during the scroll (user removes the finger, but momentum is still scrolling). Event fires at the end of momentum. Do you have any solution for this? Thank you ---
