In this work we will extend the inert-doublet model (IDM) by adding a new gauge symmetry to it, under which, a 
even scalar (
) and odd right handed component of two exotic charged leptons 
, are charged. We also add one even real scalar (
) and one complex scalar (
), three neutral Majorana right handed fermions (
), two left handed components of the exotic charged leptons 
as well as 
are all odd under the , all of which are not charged under the . With these new particles added to the IDM, we have a model which can give two scalar DM candidates, together they can explain the present DM relic density as well as the muon (g-2) anomaly simultaneously. Also in this model the neutrino masses are generated at one loop level. One of the most peculiar feature of this model is that non-trivial solution to the axial gauge anomaly free conditions lead to the prediction of a stable very heavy partner to the electron (
), whose present collider limit (13 TeV LHC) on its mass should be around 
few TeV.
