window.location does not Redirect with Ajax

I have a page with several user controls that use Ajax. When I try to do window.location from this page, Ajax traps the call and does not allow the redirect.

               $.ajax({
                        url: 'assets/php/action.php',
                        method: 'post',
                        data: $("#register-form").serialize()+'&action=register',
                        success:function(response){
                            $("#register-btn").val('Sign Up');
                         //   console.log(response);
                         if(response === 'register'){
                             alert("you will now be redirected");
                             window.location = 'home.php';
                            }
                            else{ 
                            $("#regAlert").html(response);
                         }
                        }
                    });

Use this rather window.location.href = 'home.php';
