Как добавить строку динамически в наборе форм django

В моем приложении django у меня есть две модели, т.е. Product и Real, которые связаны отношениями "многие ко многим".

Для динамического добавления данных в мои таблицы я хочу использовать javascript для добавления строки или удаления строки в моих формах, но не могу этого сделать.

Вот подробности:

Models.py

from dataclasses import Field
from django.db import models

class Product(models.Model):
    name = models.CharField(max_length = 150)
    quantity = models.IntegerField()
    cost = models.DecimalField(max_digits=15, decimal_places=0)
    sell = models.DecimalField(max_digits=15, decimal_places=0)

class Real(models.Model):
    payment_id = models.CharField(max_length = 150)
    company = models.CharField(max_length = 150)
    product = models.ManyToManyField(Product, symmetrical=False)

Forms.py

from .models import Product, Real
from django import forms
from django.forms import formset_factory

class ProductForm(forms.Form):
    name = forms.CharField()
    cost = forms.DecimalField()
    sell = forms.DecimalField()
    quantity = forms.IntegerField()

ProductFormset = formset_factory(ProductForm)

class RealForm(forms.Form):
   payment_id = forms.CharField()
   company = forms.CharField()
   product = ProductFormset()

Views.py

from django.shortcuts import render, redirect
from django.forms import modelformset_factory
from .models import Product, Real
from .forms import RealForm, ProductForm, ProductFormset

def post(request):

   if request.POST:
        form = Real(request.POST)
        form.product_instances = ProductFormset(request.POST)
        if form.is_valid():
            real = Real()
            real.payment_id = form.cleaned_data['payment_id']
            real.save()

        if form.product_instances.cleaned_data is not None:

            for item in form.product_instances.cleaned_data:
                product = Product()
                product.name = item['name']
                product.cost = item['cost']
                product.sell = item['sell']
                product.sell = item['quantity']
                product.save()
                real.product.add(product)
            real.save()

   else:
        form = RealForm()
        return render(request, 'test.html', {'form':form})

def my_formset_view(request):
    response = None
    formset_class = modelformset_factory(model=Product, fields=('name', 'cost', 'sell'), extra=0, can_delete=True)
    if request.method == 'POST':
        formset = formset_class(data=request.POST)
            
        if formset.is_valid():
            formset.save()
            response = redirect(to='my_success_view')
    else:
        formset = formset_class()
        
    if response is None:
        response = render(
            request, 'test.html', dict(formset=formset))
        
    return response

test.html

но django ничего не выводит
