I Can't get a dynamic radiobox value using Django

Question

Hello everyone.

I have a dynamic formulary that when a user types a query, it shows some radio box. And i get this error when i submit the form:

MultiValueDictKeyError at /add_company/ "Key 'radioramo' not found in < QueryDict:...

A sample of my javascript code:

var elem = document.getElementById('div_field');
var radio_ramo = document.createElement("input");
radio_ramo.type = "radio";
radio_ramo.name = "radioramo";
radio_ramo.id = "radioramo";
radio_ramo.value = $(aux).find(tag).text();
elem.appendChild(radio_ramo);

In my views.py I have this:

def add_company(request):
    if request.POST:
        cform = CompanyModelForm(request.POST) 
        ramo = request.POST['radioramo']
        if cform.is_valid():
            newCompany = cform.save(commit= False)
            newCompany.ramo = ramo
            newCompany.save()
            cform.save_m2m()

Django didn't recognize the new tag "radioramo". Anyone knows how can I get the selected radio value?

I appreciate any help. Thank you!
