window.history.pushState

I'm using the pushState function to populate history , so alright, but it's time to use windows.history.back() only to go back once. The function you add is as follows:

function activate_page(sel, have_state)
{
    var $dn = $(sel);
    var is_vis = $dn.is(":visible");
    if(!is_vis)
    {
        $dn.parents("body").find(".upage").addClass("hidden");
        $dn.removeClass("hidden");
        window.history.pushState({upage:sel}, sel, document.location.origin + document.location.pathname +sel);
        $(document).trigger("pagechange");
    }

}

And to go back I use:

angular.module('ionic')
  .run(function($ionicPlatform,$ionicPopup, $state,$ionicHistory){
    $ionicPlatform.registerBackButtonAction(function (event) {
      //console.log(window.history);
      if($state.current.name=="app.listar_CELULAS"){
        alert("entro aqui");
        navigator.app.exitApp();
      }
      else {
        window.history.back();
      }
    }, 100);
});

I need it to come back all the way to the beginning of the stack, the way it is doing it, it only returns one page.

Thank you in advance.
