Do nothing when I click

Hello,

I've been install the extension on Bracket's latest version: Version 1.12 édition 1.12.0-17621 (release d3b783b99)
But when I clicked on the check button in sidebar, I can't see nothing

I had the same problem and solved it (somehow). After installation I closed Brackets and re-opened it again. Then it worked.
