Druid Slider issue

Questions
#1

I want to integrate slider with scroll, the slider works with the scroll but while moving slider the scroll doesn’t respond. What’s the issue?

    local scrollbar_slider = self.druid:new_slider("scoreboard/slider_tab", vmath.vector3(0, -302, 0), function(_, value) 
    		scroll_window:scroll_to_percent(vmath.vector3(0, value, 0), true)
    	end)
    		scroll_window.on_scroll:subscribe(function(_, point)
    		scrollbar_slider:set(1 - scroll_window:get_percent().y, false)
    	end)
