Slider - if multiple sliders are created, values should be able to be changed for all of them

If I have two elements with class 'test', and I create a slider with $('.test').slider();, UI will create two sliders, and they will both work, except that they don't automatically update each other. When I try to manually update by targeting the change event and calling moveTo, I get recursion errors. There should be a way to manually update the value of all sliders that are created. Or, multiple sliders created with one $.slider call should be bound to each other and both sliders should move in tandem with one another.
