Problem in labeling in globe control

I want to put some labels in globe control in order ot specify some positions. As we have "Label Features' option in ArcGlobe, I think to add a featurelayer with fields in globe control, then label it should be workable and this should be similar to map control. Then I use following code:

            //add an featurelayer
            IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
            IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(@"D:\ARCGIS_SampleMaps\Data\USA", 0);
            IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
            IFeatureClass pFC = pFeatureWorkspace.OpenFeatureClass("USstates");

            IFeatureLayer pFLayer = new FeatureLayerClass();
            pFLayer.FeatureClass = pFC;
            pFLayer.Name = pFC.AliasName;
            ILayer pLayer = pFLayer as ILayer;

            GlobeControl.Globe.AddLayerType(pLayer, esriGlobeLayerType.esriGlobeLayerTypeDraped, false);
            //MapControl.AddLayer(pLayer);
            mainGlobeMap.Refresh();

            //labeling Feaatures
            IGeoFeatureLayer pGeoFeatureLayer = pLayer as IGeoFeatureLayer;
            IAnnotateLayerPropertiesCollection pAnnotateLayerPropertiesCollection = pGeoFeatureLayer.AnnotationProperties;

            IAnnotateLayerProperties pAnnotateLayerProperties;
            IElementCollection pElementCollection = new ElementCollectionClass();
            IElementCollection puElementCollection = new ElementCollectionClass();

            ILabelEngineLayerProperties pLabelEngineLayerProperties;
            pAnnotateLayerPropertiesCollection.QueryItem(0, out pAnnotateLayerProperties, out pElementCollection, out puElementCollection);
            pLabelEngineLayerProperties = pAnnotateLayerProperties as ILabelEngineLayerProperties;
            pLabelEngineLayerProperties.Expression = "[" + "STATE_NAME" + "]";

            pGeoFeatureLayer.DisplayAnnotation = true;
            GlobeControl.Refresh();

    This code works well in map control, but fails in globe control: featurelayer is added in without any labels shown. Do I miss something? Could someone show me some examples?
    THX.. 🙂

    P.S: Are there ways to add advanced labels like billboarded labels in [URL="http://blogs.esri.com/esri/arcgis/2011/01/18/labeling-in-arcglobe/http://"]?
