SortOrder for Contact model display label not giving value

[vaibhav.sood]

sortOrders:[
SortOrder {
detail: ContactDetail.Name
caseSensitivity: Qt.CaseInsensitive
field:Name.DisplayLabel
direction: Qt.AscendingOrder
}
]


This is a sort order being used for sorting the contact model based on the display label. however the contacts are not getting sorted.
Name.FirstName and
Name.LastName work perfectly but display label is not being read . Any help is much appreciated.
