Problem form submit Html.BeginForm

I have estimated the problem siginete

I have a form within a project "site1" which when you submit has to go to an external site for that post by method I am using the following statement:

@ using (@ Html.BeginForm (new @ action = "https://www.sitiodos.html"))

my problem is that when clicking the submit borotn only refreshes the page and does not execute the action that would https://www.sitiodos.html

I tested
@ Html.BeginForm
@ Html.BeginFormSitefinity

and either to run

Anyone know why this happens greetings
