Issues assigning form GET action with JQuery and Pug

I am attempting to set the action of a GET method on a forum in JQuery, however the forum is not updating/ the button associated with the form is not sending a GET request. I am unsure as to what I am doing wrong.

Am I doing something wrong in how I am assigning the new action?

Here is my code.

extends layout
block content
    script.
        var accountType = "";
        $( document ).ready(function(){
            $(".userDetails").hide();
            $(".radio-inline").change(function(){
                $(".userDetails").show();
                accountType = $(".radio-inline:checked").val();
                if(accountType == "Student"){
                    $(".userDetails").attr("action", "/api/student");
                    $(".userDetails").attr("method", "GET");
                }
                else if(accountType == "Instructor"){
                    $(".userDetails").attr("action", "/api/instructor");
                    $(".userDetails").attr("method", "GET");
                }
                else if(accountType == "Admin"){
                    $(".userDetails").attr("action", "/api/admin");
                    $(".userDetails").attr("method", "GET");
                }
            });
            $("input").change(function(){
                if(accountType == "Student"){
                    var url = "/api/student/"+ $('#name').val() + "/" + $('#password').val();
                    console.log(url);
                    $(".form-signin").attr("action", url);
                }
                else if(accountType == "Instructor"){}
                else if(accountType == "Admin"){}
            });
        });

    h2(class="form-signin-heading")

    form.form-signin(method="GET")
        h2 Select Account
        label.radio-inline Student
        input.radio-inline(type="radio" name="type" value="Student")
        label.radio-inline Instructor
        input.radio-inline(type="radio" name="type" value="Instructor")
        label.radio-inline Admin
        input.radio-inline(type="radio" name="type" value="Admin")
        br
        label.sr-only(for="inputUser") Username
        input.form-control(type="user" id="name" 
        placeholder="Username" required autofocus)
        label.sr-only(for="inputPassword") Password
        input.form-control(type="password" id="password" placeholder="Password" required autofocus)
        br
        btn.btn-lg.btn-primary.btn-block.btn-default(type="submit") Sign in
        br
        a(href="/make_account") Not a member?
