Add a feature to mark attendance from csv files

Update Attendance says: Error. Please try again

File staff_update_attendance.html (line 184):

        $.ajax({
            url: "{% url 'update_attendance' %}",
            type: 'POST',
            data: {
                date: attendance_date,
                student_ids: student_data,
            }
        }).done(function (response) {
            **if (response == 'OK'){** # Why does it check if the response is "OK" if the response is just HTML page
                alert("Updated")
            }else{
                alert("Error. Please try again")
            }
            location.reload()

It just returns HTML not 'OK'
