Attribute Value Change through API does not update the dwg view

I tried to change attribute value using the API. According to what I read in Visual Basic, I was able to edit and attribute values correctly. But the drawing does not should the updated values. Instead shows previous values.

 

The only way I was able to show the updated values is by exploding the block and then making the block again. Anyone one has any idea why? I am new to draftsight API. Any help is appreciated. Thank you.

'Get selected entities and update attribute value
For index As Integer = 0 To count - 1
   Dim entityType As dsObjectType_e
   Dim selectedEntity As BlockInstance =    dsSelectionMgr.GetSelectedObject(dsSelectionSetType_e.dsSelectionSetType_Previous, index, entityType)
   dsBlkDefinition = selectedEntity.GetBlockDefinition

   dsVarAttrDefinitions = dsBlkDefinition.GetAttributeDefinitions

   Dim attributeName As String
   Dim attributeValue As String
   For attIndex = LBound(dsVarAttrDefinitions) To UBound(dsVarAttrDefinitions)
      dsAttrDefinition = dsVarAttrDefinitions(attIndex)
      attributeName = dsAttrDefinition.Name
      attributeValue = dsAttrDefinition.Value
      If attributeName = "LINE" Then
         dsAttrDefinition.Value = "1111"
      End If

   Next
Next
