Moving branch nodes up/down not reflecting in tree

Question

The dataprovider to tree is an xml which is bindable.
When i print after adding dragged item at the dropped index
and remove the dragged item, the tree shows correctly i.e.,
print tree using trace.
but nothing gets reflected in the screen.
heres the code below:
var dropTarget:Tree = Tree(event.currentTarget);
var dropIndex:int = dropTarget.calculateDropIndex(event);
dropTarget.selectedIndex = dropIndex;
var droppedItemNode:XML = dropTarget.selectedItem as XML;
var droppedItemLabel:String = droppedItemNode.@label;
var droppedItemParentNode:XML = droppedItemNode.parent() as
XML;
var droppedItemParentLabel:String =
droppedItemParentNode.@label;
// onDragDrop(event)
// add to drop target
var insert:XML = draggedItemNode;
var inserted:Boolean =
dropTarget.dataDescriptor.addChildAt(droppedItemParentNode, insert,
(dropIndex));
trace("insert " + insert);
trace("inserted at " + droppedItemParentNode + " index: " +
dropIndex);
// remove from dragsource.
var children:XMLList =
XMLList(draggedItemParentNode).children();
for(var j:int=0; j < children.length(); j++) {
if( children[j].@label == draggedItemLabel) {
trace("removed from dragsource: " + children[j]);
var del:Boolean = delete children[j];
break;
Please advice.
Thanks,

Hi Jinsuh,
I have coded it manually (don't know if there's another way), but here's the code I've used.
If pVal.ItemUID = "m_List" Then
    If pVal.CharPressed = 38 Then 'up
        oForm = oApplication.Forms.ActiveForm
        oMatrix = oForm.Items.Item("m_List").Specific
        If (pVal.Row <> 0) Then
            oMatrix.Columns.Item(pVal.ColUID).Cells.Item(pVal.Row - 1).Click(SAPbouiCOM.BoCellClickType.ct_Double)
        End If
    ElseIf pVal.CharPressed = 40 Then 'down
        oForm = oApplication.Forms.ActiveForm
        oMatrix = oForm.Items.Item("m_List").Specific
        If (pVal.Row <> oMatrix.RowCount) Then
            oMatrix.Columns.Item(pVal.ColUID).Cells.Item(pVal.Row + 1).Click(SAPbouiCOM.BoCellClickType.ct_Double)
        End If
    End If
End If
Hope it helps,
