This glue works very well, although it's expensive. It's a type of fast-drying CA glue that's specifically designed to stick to things like silicone. Silicone caulk/adhesive also works well, but takes a long time to cure. One option is to sparingly use the CA glue to tack down the strip, and then apply silicone caulk along the edges. You can transfer the caulk to a small plastic syringe with a fine tip to get into tight places.
