pagination and X-Total-Count

I’ve modified my REST server to provide the X-Total-Count header as described in the ng-admin doc, but it seems restangular somehow doesn’t handle it correctly.

as you can see chrome shows the header, but ng-admin doesn’t recognize it. I’ve added this function to the listview:

listView.totalItems(function(response) {
     console.log(JSON.stringify(response.headers()));
     return response.headers('X-Total-Count');
 });

and it shows just these headers:

{"date":"Tue, 06 Jan 2015 13:20:45 GMT","content-length":"12373","content-type":"application/json"}

is there a solution or a workaround for this? I’ve checked my code to see if I accidentally set some wrong configuration but I really can’t figure it out… any help is really appreciated 😃
