Knockout-Kendo RadialGauge pointer transition not working

Knockout-Kendo RadialGauge pointer transition not working

Can anyone explain why this
js:
var ViewModel = function() {
this.myValue = ko.observable(25);
};
ko.applyBindings(new ViewModel());
html:
<div data-bind="kendoRadialGauge: myValue"> </div>
will allow the pointer to transition nicely to the new value, when the
databound value changes.
However when passing additional options, like this
js:
var ViewModel = function() {
this.myValue = ko.observable(25);
//various gauge settings omitted for brevity
this.pointerOptions = ko.computed(function() {
return { color: this.pointerColor(), value: this.myValue() };
}, this);
};
ko.applyBindings(new ViewModel())
html:
<div data-bind="kendoRadialGauge: { value: myValue, gaugeArea:
gaugeOptions, pointer: pointerOptions }"> </div>
...the pointer just jumps immediately to the new value.
