Winjs listview with listlayout and 2 items in one row

I am using winjs listview to show a list of items with listview layout and i need to show 2 items in a single row .I achieved it by styling the .wincontainer ,width to 50% and setting display to inline block.Its showing perfectly now.The issue am facing is that when items are completely loaded and when i scroll down half of the list view is showing empty.That is its showing double the scroll height than needed.When i go through the documentation I found that listview cell height is calculated based on the first items height and the scroll height is also calculated using that .Am aligning 2 items in row. So as far as i understand height calculation causes this issue.Is there any way i can solve this issue.This video shows the exact issue am facing
