Is Automatic Brace Completion working correctly in JavaScript

Hi,

I am a CMU graduate. Recently, I want to use VS to write my javascript program.

One thing really confuses me: is the Automatic Brace Completion really working?

It seems so according to the following youtube link:

                https://www.youtube.com/watch?v=ct4oW_cRMMw

                at 02:10, and

                https://www.youtube.com/watch?v=S5pXzp2PePw

                at 17:50

but I definitely check the box in Option->TextEditor->JavaScript->Automatic Brace Completion

I installed node js tool: NTVS.1.2.RC.VS.2015

Using VS 2015 Community under windows 10

Test this feature by creating an Express application and a blank javascript visual

And I have reinstalled the VS already... and this feature in C++ and C# are working

is there any trick I missed ?

I really really really need this feature. This is the only flaw so far to develop a javascript program in VS

Please help
