Generic Action in Play Framework controller

Question

I have a request form on two pages of my site: About us and Contacts. Actions for both of them described in my Home controller. After submitting the form I call sendRequest method, which checks form errors and sends request. This method looks like:

def sendRequest = Action {implicit request =>
  requestForm.bindFromRequest.fold(
    formWithErrors => {
      BadRequest(views.html.Home.contacts(formWithErrors))
  },
  response => {
    Redirect(routes.HomeController.contacts().flashing("success" -> "OK"))
  }
)

}

In this method I define view and route to navigate. And for my About us page I should do the same work, but call about us view and route.

How could I create generic method and call it with concrete view and route as parameters?

// if requestForm is a Form[A]

protected def genericMethod(
    view: Form[A] => play.twirl.api.Html, route: play.api.mvc.Call) = 
  Action {implicit request =>
  requestForm.bindFromRequest.fold(
    formWithErrors => {
      BadRequest(view(formWithErrors))
  },
  response => {
    Redirect(route.flashing("success" -> "OK"))
  }
  )
}

def sendRequest = genericMethod(
  views.html.Home.contacts, 
  routes.HomeController.contacts())
