Cotonester doesn't usually require much fertilization, but since yours isn't blooming, try a light dose of fertilizer.
Also, check to make sure it isn't rootbound and in need of repotting.
Cotoneaster needs at least part shade to thrive. Is your cotoneaster getting enough sun?
Another thing you can do is have your soil tested. Perhaps important nutrients are lacking.
