coronaui_scrollView does not scroll!

A bit of a problem for a scrollView to not scroll. Please tell me what I’m doing wrong.

local ScrollView = require("coronaui\_scrollView")  
   
local topBoundary = 60 --I've tried many different values for this  
local bottomBoundary = 160 --I've tried many different values for this  
local scrollView = ScrollView.new{ top=topBoundary, bottom=bottomBoundary }  
scrollView.x = 60  
scrollView.y = 60  
   
local myGroup = display.newGroup()  
  
local yPos = 0  
local spacing = 140  
for i = 1,3 do  
 local rect = display.newRect( 0, yPos, 100, 100 )  
 rect:setFillColor(255, 0, 0)  
 yPos = yPos + spacing  
 scrollView:insert(rect)  
end  
   
local scrollBackground = display.newRect(0, 0, 250, scrollView.height+64)  
scrollBackground:setFillColor(255, 255, 255)  
scrollView:insert(1, scrollBackground)  
  
myGroup:insert(scrollView)
