How to use Django Formset in Formwizard

Question

I have created a from wizard with 3 steps forms, on this second step I have a using a Formset which is dynamically updating. I am able to get the step1 & step2 data in the form list done() method but Formset(ProductAttributeFormset) data is not getting. How can I process the ProductAttributeFormset data?

My Form as follows:

from django.db.models import fields
from django import forms
from django.forms import formset_factory
from django.db.models.fields import CharField
from .models import Product,Category,Attribute,ProductAtribute

class createProductForm(forms.ModelForm):
    title = forms.CharField(label = ("Product Name"),required=True)
    category = forms.ModelChoiceField(queryset=Category.objects.filter(status=True),required=True,widget=forms.Select(attrs={'class': ''}))
    class Meta:
        model = Product
        labels = {
            "product_image": "Image"
        }
        widgets = {
            'product_image': forms.FileInput(),
        }
        fields = ['title','product_slug','in_stock','category','product_image','description']

class createSEOForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = ['meta_title','meta_keyword','meta_description']

class createAttributeForm(forms.ModelForm):
    class Meta:
        model = Attribute
        fields = ['name']

class createProductAttributeForm(forms.ModelForm,forms.Form):
    class Meta:
        model = ProductAtribute
        widgets = {
            'image': forms.FileInput(),
        }
        fields = ['image','sku','price','offer_price','attribute','attribute_value']

ProductAttributeFormset = formset_factory(createProductAttributeForm, extra=2)

My view file as follows:

from django.shortcuts import render
from formtools.wizard.views import SessionWizardView
# Create your views here.
from django.shortcuts import redirect, render

                product_attribute_instance = ProductAtribute.objects.get(product_id=self.kwargs['id'])
            else:
                product_instance = Product()

        except Exception as e:    
            product_instance = Product()

           
        for form in form_list:

        product_instance.save()
        

        return redirect('list')
