How can I make the Duplicated Geometry displayed in custom component?

I created a custom component as below.

But the out Geometry is not displayed though It can be used by other component.

End Sub

Protected Overrides Sub RegisterOutputParams(ByVal pManager As Grasshopper.Kernel.GH_Component.GH_OutputParamManager)
pManager.Register_GeometryParam("OutGeometry", "G", "Translated Geometry")
End Sub

Dim g As GeometryBase = Nothing
Dim crv As Curve = Nothing
DA.GetData(0, g)
DA.GetData(1, crv)
Dim out = g.Duplicate
out.Translate(crv.PointAtEnd - crv.PointAtStart)
