I'm wrong, is there a right way to use it

If you would like us to spend some time helping you to diagnose the problem, please spend some time describing it using proper GH syntax highlighting for code and do not post images.
Please also take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem. In general we prefer to use GitHub issues only for bugs and enhancements.

Sorry.It's my problem.
