doesn't detect change if using manifest file

I’m using a manifest scss file to import multiple scss files in a file called application.scss to sort of mimic an asset pipeline.

@import "variables";
@import "theme";
@import "responsive";
...

then i have this in functions.php
wp_register_style( 'application', get_stylesheet_directory_uri() . '/scss/application.scss' );

If i make a change to, for example “theme”, i have to clear the cache in the plugin admin to recompile. Is there any way for the plugin to detect changes in the imported scss files. I know its not a big deal but coming from the the rails world scss changes are detected automatically.

Thanks.
