Django + Ajax Is the request correct?

Question

JavaScript

Good afternoon dear forum users. I ask you not to throw tomatoes, I'm just learning. Problem with ajax requests. More precisely, as I understand it, they are lost or do not go there. Because on success, my JS reloads the page, it reloads, i.e. the script is executed and sent. And here record in a DB does not change.
CRM my application is located at {{url}}/crm. And it already has subtabs, i.e. {{url}}/crm/my_work is the path of the tab I dropped here. Please explain what's what, and with a complete code example or correction of mine, please, so that I can figure it out. I am attaching the code:
views.py

def NBEdit(request):
    if request.method == "POST" and request.is_ajax():
        MD = MyDela(
            pk=request.POST.post("id", ""),
            name=request.POST.post("name", "")[:250],
            information=request.POST.post("info", "")
        )
        MD.save()
        return HttpResponse("ok")
    else:
        return HttpResponse("bad")

models.py

class MyDela(models.Model):
    name = models.CharField(max_length=250)
    kr_info = models.CharField(max_length=300)
    date_firstly = models.DateTimeField(auto_now_add=True)
    date_edit = models.DateTimeField(auto_now=True)
    information = models.TextField()
    status = models.IntegerField()
    user = models.ForeignKey(User)

urls.py of my application, NOT the ENTIRE PROJECT

urlpatterns = patterns('',
    # ex: /cab Klients/
    url(r'^$', views.main, name='crm_main'),
    url(r'^my_work/new', views.ValidLoginMain, name='crm_new_NB'),
    url(r'^my_work/newNB/', views.NBEdit, name='crm_NBEdit'),
)

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>

                            cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                            break;
                        }

                    // Only send the token to relative URLs i.e. locally.
                    xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));

Change request.POST.post("id", "") in the view to request.POST.get("id", "") (and the same for everyone else)
