How to add new form to django formset and not lose user input from previous forms

Question

If user adds another form to formset, but has already typed something in first form, then the input will be lost, as new form was created. User now has 2 empty forms. Is there a way to add new form to formset but not lose user input?

forms.py

class Form(forms.Form):
    client = forms.CharField(label='Client', required=False)
    end_client = forms.CharField(label='End client', required=False)
    product = AutoCompleteSelectField(lookup_class=ProductLookup, label='Model', required=False)

views.py

def get(self, request):
    request.session['form_count'] = 1

    FormSet = formset_factory(Form)
    formset = FormSet()

    return render(request, self.template_name, {'formset': formset} )

def post(self, request):
    if "add-form" in request.POST:
        form_count = request.session['form_count']
        print("There are " + str(form_count) + " forms")

        form_count = form_count + 1
        request.session['form_count'] = form_count
        print("Form count increased by 1, form count is: " + str(form_count))

        FormSet = formset_factory(Form, extra=int(form_count))
        formset = FormSet()  **<-- if I put request.POST in here, new form will not be created**

        return render(request, self.template_name, {'formset': formset})

html file

<div class="content">
  <form method="post">
    {% csrf_token %} {{ formset.management_form }}
    <div class="form-group">
      {% for form in formset.forms %}
      <table class='no_error'>
        {{ form.as_table }}
      </table>
      <br>
      <br> {% endfor %}
    </div>
    <input class="btn btn-primary" type="submit" value="Submit order" />
    <input name="add-form" class="btn btn-primary" type="submit" value="Add new product" />
  </form>
</div>
