Basically I have a timeline with posts that is a $firebaseArray and any change to this array is getting binded properly. But when I want to bind any other data it only binds when ngInfiniteScroll is trying to retrieve more data from firebase, so only when I scroll down.
In the code bellow I'm calling {{getMoreDetails()}}
and this data is binded when the first set of data is being retrieved with ngInfiniteScroll but as soon as it is loaded the bind breaks and only binds again when scrolling.
My concerns here are:
- Was ngInfiniteScroll designed to work this way?
- Is there any workaround in this scenario?
Stack:
"firebase": "2.4.2","angularfire": "~1.2.0","firebase-util": "0.2.5","ngInfiniteScroll": "1.2.2"
