Declare a .js file in .qmldir but the QtCreator has no auto-completion with .qml file

For more details:

I have a project with QtWidget and Qml

In my qml include directory，i have some .qml and .js files and i declare the the files in qmldir as a module.

When i import this module and try to use the functions in js ,QtCreator cannot highlight and auto-complete,but the qml components in this module works fine.
