I try to use scala forms in play framework but browser throws "Action Not Found"

Scala
1def add = Action{ implicit request : MessagesRequest[AnyContent]=>
2    Ok(views.html.listLogin(login, form,postUrl))
3  }
4
5  def save = Action { implicit request: MessagesRequest[AnyContent] =>
6    val errorFunction = { error: Form[Data] =>
7      BadRequest(views.html.listLogin(login,form,postUrl))
8    }
9
10    val successFunction = { data: Data =>
11      val widget = Login(username = data.name,
12        password = data.password)
13      login.append(widget)
14      Redirect(routes.LoginController.save()).flashing("info"-> "Account Created..")
15    }
16    val formValidationResult = form.bindFromRequest
17    formValidationResult.fold(errorFunction,successFunction)
18  }

Play
1@(widget : Seq[Login] , form: Form[LoginForm.Data], postUrl: Call)(implicit request: MessagesRequestHeader)
