Slider with Two Handles, each with their own range

Slider with Two Handles, each with their own range

Using ui slider 1.5.2 and ui core 1.5.2, we were able to create a slider with 2 handles, each handle having a different range as shown below.
If I understand correctly, the option shown below, ie using "handles:", does not seem to be available in 1.8.2, but instead you need to use values: [x,y] to create 2 handles. Is this correct ?
Secondly, does n't using "values: [x,y]" create 2 handles with the same range ?
Thanks very much in advance

sliderContainer.slider(
{
            ...
            change: etc
            slide: etc
            ...
            range: true;
            handles:
            [
                {
                    value: currentMinHandleIndex,
                    min: 0,
                    max: histoSlider.rangeDimVals.length - 1
                },
                {
                    value: currentMaxHandleIndex+300,
                    min: 2,
                    max: histoSlider.rangeDimVals.length + 1
                }
            ]
        });
