How to use this in Angular?

Hi! I have just tried to use your library for my Angular app. But somehow it does not work for me..
I have included your js and css files in my app, and the structure of my modal and body html should also be compatible to your css, still i do not see the effect.. Can you please tell me why you do not have to call the function disableBodyScroll?

Hi, did you include Bootstrap? Does my demo work for you? Can you show your app? Regards
