Get variables in datables passed by django

I am using jquery datatables in my django app. every row in my table have a named url to another page together with the object. {% url 'obj_details' obj.id %}. When I click on the url I am getting no reverse match found error. I have inspected the issue in detail. The url obj_details is a named url that exists in the urls.py

url(r'^obj/(?P<pk>[\w-]+)/details$', objDetailsView.as_view(), name='obj_details')

datatables uses another view to get the required data it is as pasted below

def objdtable(request):

obj_json_tuple = list(Obj.objects.all().values_list("objnum", "ob_field", "date", "price", "field2", "seller", "id"))

return HttpResponse(json.dumps(obj_json_tuple))

I am displaying all fields except id in datatables without issues.

"columns": [
                   { "": "fields.objnum"},
                   { "": "fields.ob_field" },
                   { "": "fields.date" },
                   { "": "fields.price" },
                   { "": "fields.field2" },
                   { "": "fields.seller" },
           ]

How can I pass id returned by objdtable view as an argument to url obj_details? I have tried {% url 'obj_details' fields.id %} and {% url 'obj_details' id %} but bothe are giving no reverse match found errors. Then I tried in datatables

"data":
         {
         'bid':fields.id
         }

and changed the named url to the link obj/data/details I have also tried changing data to fields.id but nothing worked. How can I access a variable passed by django in datatables? I can use that variable in url so that the issue could be solved.
