How do we make a htmx response trigger a form reset?

Question

I am creating a very basic Django messaging application, and would like to use htmx to send and render messages. I am able to post, save the message, and render the partial message without issue. However, I am running into a weird problem where my form textarea is not being reset. So, I would send a message, and after the swap is inserted, my old message would still be in the textarea. This isn't very ideal!

I tried to manually clear the textarea by adding an onclick event like so:

Html

<div id="new-message-div"></div>


<form id="message-form" class="chat-form rounded-pill bg-dark" data-emoji-form="" hx-post="{% url "chat:create-message" object.pk %}" hx-target="#new-message-div">
...

{{ message_form }}

...

<button class="btn btn-icon btn-primary rounded-circle ms-5" type="submit" onclick="submitForm()"> </button>
</form>

Script (https://stackoverflow.com/a/14589251/12758446)

<script>
function submitForm() {
   var message_form = document.getElementById('message-form');
   message_form.submit(); // Submit the form
   message_form.reset();  // Reset all form data
   return false; // Prevent page refresh
}
</script>

Despite having the message_form.submit() in the submitForm(), my form is not being submitted, but the textarea is getting reset.

Question:

How would I go about getting my textarea reset after successfully sending and rendering a message?

Django view, based off of https://github.com/legionscript/socialnetwork/blob/84375841429887e394a2a31e1b67919f81a3cb06/social/views.py#L428

def create_message(request, pk):
    message = None

    if request.htmx:
        thread = get_object_or_404(ThreadMessageModel, pk=pk)
        form = MessageModelForm(request.POST)

        if thread.receiver == request.user:
            receiver = thread.user
        else:
            receiver = thread.receiver

        if form.is_valid():
            message = form.save(commit=False)
            message.thread = thread
            message.sender_user = request.user
            message.receiver_user = receiver
            message.save()

        form = MessageModelForm()

        return render(request, 'chat/subtemplate/render_message.html', {'message': message})

This also works:

<form hx-put="/" hx-on::after-request="this.reset()">
...
</form>
