Need an example for RadListView with http fetch #1406

Hello,

i cannot find any example here: https://github.com/NativeScript/nativescript-ui-samples-angular/tree/master/listview/src/app/examples with remote datasource fetch only with setTimeout. Why do i need that? because there is ObservableArray used and i do not know if it plays some big role in not rerendering all items / in updating just one item etc. Problem is that when i have my list items in state and i update state all items in list are rerendered however in plain angular with *ngFor trackBy only item that changed is rerendered.

I am not getting console.log in trackBy function. It seems that trackBy has no effect.
