Delete the Error class as soon as the user begins entering text into the input field

Currently, I am utilizing an ajax call to submit a FORM. My goal is to highlight any inputs that fail validation and then remove the highlight as soon as they begin entering information into the input field. While I am successful in adding the error class, I have been facing challenges in removing it. Despite trying various approaches such as keydown, keypress, keyup, change, and focus events, I have not achieved the desired outcome.

In all my attempts, either nothing occurs or the alert only triggers once immediately after submission.

Below is my current implementation:

$(document).ready(function() {
$('#config_form_submit').off().click(function(e) {
    e.preventDefault();
    $('#config_form').submit();
});


function removeErrorClass() {
    alert($(this).html());
}

// $("input .error").keyup(removeErrorClass());
//$("input .error").change(removeErrorClass());
//$("input .error").keydown(removeErrorClass());
//$(".error").on(keypress, removeErrorClass());


$('#config_form').off().submit(function(e) {
    e.preventDefault();
    $.ajax({
        type:"POST",
        url: $('#config_form').attr('action'),
        data: $(this).serialize(),
        datatype: 'json',
        success: function(data) {
            $("#config_results").text(data.message);
            if(data.errors.length > 0)
                for(index in data.errors) {
                    $("#id_"+data.errors[index]).addClass("error");
                    $("#id_"+data.errors[index]).bind("input", removeErrorClass());
                }
        },
    });
});
}); //document.ready

My solution was inspired by billyonecan's answer:

$(document).on("keyup", "input.error", function(){
    $(this).removeClass("error");
});
