Refresh observableArray when items are not observables

Question

Basically I have an observableArray and the values for each item are not an observable. This means when I change an item value the UI within a foreach loop of the observable

Answer 1

I ended up using the dirty approach from above but made it so that all my observable arrays had this functionality.

ko.observableArray.fn.refresh = function () {
        var data = this().slice(0);
        this([]);
        this(data);
    };

The valueHasMutated didn't work for me. Its kind of lame the entire list has to be updated. Or in my case find a way to extend the ko mapping plugin to fill the observable arrays with observable objects..
