XHR status returns 0 in ajax call to a django generic view -

this totally weird because don't know why returning error when replicated same code 1 section another, change title of generic views (updateview) , never execute function return form edit single customer, that's code:

urls

from django.conf.urls import patterns, include, url django.contrib.staticfiles.urls import staticfiles_urlpatterns . import views . import forms . import invoice   urlpatterns = patterns('',     url(r'^pedidos/',views.pedidoslistview.as_view(),name="pedidos_list"),     url(r'^pedidos/add',views.add_pedido, name="pedido_add"),     url(r'^pedidos/edit/(?p<pedido_id>\d+)',views.edit_pedido, name="pedido_edit"),     url(r'^pedidos/delete/(?p<pedido_id>\d+)',views.delete_pedido, name="pedido_delete"),     url(r'^pedido/(?p<pk>\d+)',forms.detailpedido.as_view(), name="pedido_detail"),     url(r'^pedido-pdf/(?p<pk>\d+)',invoice.detalle_pedido_pdf, name="pedido_detail_pdf"),     url(r'^clientes/',views.clienteslistview.as_view(),name="clientes_list"),     url(r'^clientes/edit/(?p<pk>\d+)$',forms.clienteupdateview.as_view(), name="clientes_edit"),     url(r'^empleados/edit/(?p<pk>\d+)$',forms.empleadoupdateview.as_view(),name="edit"),     url(r'^empleados/',views.empleadolistview.as_view(),name="list"),  ) 

forms

class clienteupdateview(updateview):     form_class = clientemodelform     model = cliente     template_name = 'ventas/form.html'      def get(self, request, **kwargs):         self.object = cliente.objects.get(pk=self.kwargs['pk'])         form_class = self.get_form_class()         form = self.get_form(form_class)         context = self.get_context_data(object=self.object, form=form)         return self.render_to_response(context)      def form_valid(self, form):         self.object = form.save(commit=false)         self.object.save()         return httpresponseredirect('ventas/clientes_list.html')      def form_invalid(self,form):       if self.request.is_ajax():           return httpresponsebadrequest(json.dumps(form.errors),                                        mimetype="application/json") 

javascript

$(".edit").click(function(ev){     ev.preventdefault();     var url = $(this).data('form');     $.ajax({         url: url,         success: function(data, status){             $('body').append($('<div id="mymodal" class="modal hide fade">' + data + '</div>').modal());             $("#mymodal").find(".datepicker" ).datepicker({ dateformat: "dd/mm/yy" });         },         error: function (xhr, ajaxoptions, thrownerror) {             console.log(xhr.status);             console.log(xhr.responsetext);             console.log(thrownerror);         }     })      return false; // prevent click propagation }); 

html

  <button data-form="{% url 'ventas:clientes_edit' c.id %}" class="edit btn btn-mini btn-info"> 

if in ajax url change value 'ventas/empleados/edit/someid' (the same replicated clienteupdateview, can retrieve form employee edit can't same customer, i'm missing i'm not able notice? it's driving nuts! ideas?

regards!
