TextEdit display cannot update

Hi，dear developer：

An issue was observed that the display of a "TextEdit" created by action "Element Create" cannot be updated when the related global Var, Which is the content of "Text" of "TextEdit", is updated.

In my test, this issue does not exit if the "TextEdit" is created mannaully in the scene edit interface.

This issue was firstly appeared after I updated to 5.12. But it is still there when I go back to 5.11.
