Express not render

I got a express program with use jade templates.

I have this code in app.js

app.get('/visualizar',function(req, res) {
   res.render("visualizar");
}

I have configured correctly the middlewares in the folder views.

Then, I got a page in jade that have a td and a script that make a $get to visualizar if you click in the td

$(window).load(function (){

         $('tr').click(() => { 

                 $.get("/visualizar");
         });

});

The program do the get to visualizar but not render the page, why?
