Isaac Sim 3d Text didn't change

Hi, I tried to use 3d text to display some information.
When I changed the text by program, but the 3d text didn’t change.
My Isaac Sim version is 2022.2.0 and following is my code.

TextNode_01 = self.stage.GetPrimAtPath(“/World/Dashboard/Text_04/ActionGraph/generate_3d_text”)
attr_01 = TextNode_01.GetAttribute(“inputs:text”)
attr_01.Set(“Good:1001 unit”)

And following is my test video.
