After the comment from @mrnfrancesco, i apply the following logic to save in data model:

class CreateDemandView(FormView):
...
    def form_valid(self, form):
        demand = form.save(commit=False)
        demand.save()

        format_name = self.request.POST.getlist('format_name')

        for i in format_name:
            fields_name = self.request.POST.getlist('field_name_' + i)
            format_name_id = NewFormatByStore.objects.get(pk=i)
            data_content_field = self.request.POST.getlist('field_format_data_' + i)

            j = 0 
            while j < len(fields_name):
                format_data_demand = FomartWithDataFromDemand(demand_name=demand, format_name=format_name_id, field_name=fields_name[j], field_format_data=data_content_field[j])
                format_data_demand.save()
                j += 1

...

I get the data from POST and save the respective data in model.
