Refering to related object in ListView - django

Question

I am trying to create some kind of 'panel control'. I need to manage my objects directly from ListView. I'll show you transparent (I believe) schema what I'm trying to solve.
Models
class Category(models.Model):
cat_name = models.CharField(max_length=120)
class Product(models.Model):
category = models.ForeignKey(Category)
prod_name = models.CharField(max_length=120)
Views
class CategoryListView(ListView):
model = Category
def get_context_data(self, *args, **kwargs):
context = super(CategoryListView, self).get_context_data(*args, **kwargs)
# two class based forms created for models
context['form_category'] = CategoryForm()
context['form_product'] = ProductForm()
return context
def post(self, request, *args, **kwargs):
form_category = CategoryForm(request.POST or None)
if form_category.is_valid():
new_category = form_category.save(commit=False)
new_category.save()
return redirect('category_list')
return Http404
templates
I use two modal window to open my forms which I added to my context views
<button>Modal btton opens product form</button>
{% for category in object_list %}
<div class="panel">
<div class="panel-heading">
<h3>{{ category.cat_name}}</h3>
<button>Modal btn opens product form</button>
</div>
<div class="panel-body">
<ul>
{% for product in category.product_set.all %}
<li>
<p>{{ product.prod_name }}<p>
<span>Delete</span>
{% endfor %}
</ul>
</div>
</div>
{% endfor %}
<form action="." method="POST">{%csrf_token%}
{{ form_category.as_p }}
<input type="submit" value="add category">
</form>
<form action="." method="POST">{%csrf_token%}
{{ form_product.as_p }}
<input type="submit" value="add product">
</form>
For first form (CategoryForm) it's working fine because whole page refers to that (model = Category). Now is the question - how to create second object on that page. I can do this in DetailView using urls and parameter like slug, id or pk and after passing it as value but I want to do this from that page without moving to detail page.
Secondly I was thinking how to delete products from list but there is the same problem how to let django know that witch object I would like to remove.
Thanks.
