[jQuery] Reset range slider values

I setup a slider using
jQuery(id).slider({ range:true,  min: 1, max: 100,  step: 1, values:
[1, 100]}

After I moved the slider handles I try to reset the values:
jQuery(id).slider('option', 'min', 1); //works
jQuery(id).slider('option', 'max', 100); //works
jQuery(id).slider('option', 'values', [1,100]); //does not work!

The min and max are reset but the handles stay where they are. Is this
a bug?

For single silder this works
jQuery(id).slider('option', 'value', 1);

Thanks!
