127.0.0.1:8000/api/<pk>/viewuser

urls.py

from django.conf.urls import url
from UserAPI.api import views
from  UserAPI.api.views import UserAuthAPIView

urlpatterns = [
    url(r'^$', UserAuthAPIView.as_view({'get': 'list'}), name='user-list'),
    url(r'createuser/$', views.UserAuthAPIView.createuser, name='user-create'),
    #url(r'userlogin/$', views.UserAuthAPIView.userlogin, name='user-login'),
]

views.py

class UserAuthAPIView(ModelViewSet):
    queryset = UserModel.objects.all()
    serializer_class = ListViewSerializer

    def get_object(self, queryset=None):
        return self.request.user

    @action(methods=['post'], detail=False, permission_classes=[AllowAny], serializer_class=UserSerializer)
    def createuser(self, request, *args, **kwargs):
        data = request.data
        serializer = UserSerializer(data=data)
        if serializer.is_valid():
            serializer.save()
        return Response({ "status" : "user created successfully"}, status=HTTP_201_CREATED)

Routers preform a couple of operations on the viewset and in particular add a mapping from the http verbs to the associated functions.

You need to do something similar for your action:

urlpatterns = [
    url(r'^$', UserAuthAPIView.as_view({'get': 'list'}), name='user-list'),
    url(r'createuser/$', views.UserAuthAPIView.as_view({'post': 'createuser'}), name='user-create'),
]
