Modifying an item in a WPF sorted ListView doesn't change the sort position of that item

I have a sortable listview that gets filled with a live data as it comes. Sorting works perfectly but the real problem arises when an item is modified after being added to the collection. The position of modified item does not change no matter what the sort orders is.

I have googled it but couldn't find a better solution to make my listview a perfect sorted listview.
