Hello Norm,

By design the RangeSlider's change event fires only when the user sets the value through the drag handler or the keyboard. It does not fire when the value is set programmatically (with the value or values API methods). In this case you can trigger the event if you want it to fire. I've made the respective modifications to the setStartValue and setEndValue handlers in your example so that the event is triggered after setting the value: updated dojo.
