In angular I found out you can bind a template to a function which returns an array, like this:
<div class="cal_row" id ="id_{{task.id}}" ng-repeat="task in calendar.filtered()">
<div class="id">{{task.id}}</div>
<div class="task">{{task.task}}</div>
<div class="start">{{task.start}}</div>
<div class="finish">{{task.finish}}</div>
</div>
It's pretty cool, because that way I can, for example, avoid having to keep a variable around just to maintain the filtered version of the data.
However, I also loose the binding with the original data: when the underlying data changes, I can't seem to get angular.js to spot the change, and update the view.
Is there a way to do that? I tried to find anything in the docs, but couldn't
Thanks a lot

If the model is changed, the view reflects the change and vice versa. In the above example, the {{ firstName }} expression is an AngularJS data binding expression. Data binding in AngularJS binds AngularJS expressions with AngularJS data. {{ firstName }} is bound with ng-model="firstName".
AngularJS creates a two way data-binding between the select element and the $ctrl.
As mentioned earlier, one-way data binding in Angular can be of three types i.e Interpolation, Property binding, and Event binding.
Data Binding is a way to synchronize the data between the model and view components automatically. AngularJS implements data-binding that treats the model as the single-source-of-truth in your application & for all the time, the view is a projection of the model. Unlike React, angular supports two-way binding.
If you make a change to some data from outside angular, you have to use $myScope.$apply so angular knows something has changed. http://docs.angularjs.org/api/ng.$rootScope.Scope#$apply
