Rails - Variable from controller not being passed to view

I can get an object in the view from the "new" method but cannot get it from another method from controller. Why?

So, I have this in the routes.rb:

Rails.application.routes.draw do
    get 'horarios/new'=> 'horarios#new'
    get 'horarios/newprofessor'=> 'horarios#newprofessor'
end

And this in the horarios_controller.rb:

class HorariosController < ApplicationController
    def new
        @horario = Horario.new
        @teste = "it prints!"
    end

    def newprofessor
        @teste = "it prints!"
    end
 end

And put this in both views (new.html.erb and newprofessor.html.erb):

<% raise @teste.inspect %>

The "new" view gives me the object, but the "newprofessor" view says that it's nil. Why is that? Thank you!
