The above method looks fine, though I don't know your business rules specifics.

Just some code syntax changes would be nice (like Features with capital F, is wrong casing), etc.. With regards to the call, you can't just call the above method from a View or View User control.

You have to populate the ViewData or Model with data from this method before you render the view.

An alternative would be to use JavaScript, specifically JSON calls to request data from an action that returns JsonResult or ContentResult or something similar.. Controller actions should typical return ActionResult or the type inheriting from it (ContentResult, JsonResult, RedirectToActionResult etc.)..
