Touch Scrollview event in Corona SDK?

I have a scrollview widget with one child (myrect)

I want to detect a touch-close event for "myrect", however at the moment it only detects the "initial" phase !!

here is the full code

 --main.lua
 local widget = require "widget"

 local myscrollview = widget.newScrollView{}

 local myrect = display.newRect(0, 0, display.contentWidth, 68)                  
 myrect:setFillColor(255,100,100,255)
 myscrollview:insert(myrect)

 local function ontouch(event)

    if event.phase == "ended" then
            print("event ended")
    end
end
myrect:addEventListener( "touch", ontouch )

I need basic functionality, it’s strange that the crown doesn’t support this, or maybe I’m missing something

Many thanks

Thanks, SatheeshJM is your code for some how to give me the wrong result, so when I click anywhere outside the rect, the touch end event will fire

but finally i have a solution. Just in case, if anyone is interested.

here is an extended version of the solution

local widget = require "widget"

local myscrollview = widget.newScrollView{}

local myrect = display.newRect(0, 0, display.contentWidth, 68)                  
myrect:setFillColor(255,100,100,255)
myscrollview:insert(myrect)

local function ontouch(event)

    if event.phase == "moved" then
        local dx = math.abs( event.x - event.xStart )
        local dy = math.abs( event.y - event.yStart )

        if dx > 5 or dy > 5 then
            myscrollview:takeFocus( event )
        end
    elseif event.phase == "ended" then
    display.getCurrentStage():setFocus(nil)
            print("event ended")
    end

    return true
end
myrect:addEventListener( "touch", ontouch )
