Change noUiSlider options

Hi,

I am trying to update the noUiSlider options through the code, but without success.
What is the best way of doing this?

The thing I am current doing is:
var slider = document.querySelector(‘#gsfslider’ + fieldid);

var curVal = $(‘#field_2_’ + val).val();
slider.noUiSlider.updateOptions({
padding: [0, curVal]
});
