Using Django-Angular to make a AJAX call to a view

I'm trying to use Django-Angular to make a AJAX call to a view in Django. I'm following this guide here.

However, when I make a POST I'm getting the message: CSRF verification failed. Request aborted. It seems like the action as described in the docs process_something isn't being called as I shouldn't need the token.

Can anyone spot the issue, below is what I have tried so far...

Here is the relevant js controller script:

   var in_data = {action: 'process_something', somevar: $scope.somevar};
   var post_call = CbgenRestangularDjango.all('pin-verification/').post(in_data)

and the form:

<form ng-controller="PinValidationFormCtrl"  name="CompanyValidPinForm" class="bs-callout">
        <div class="col-xs-2">
            <input class="form-control" name="somevar" ng-model="somevar" type="text">
        </div>

        <div class="col-xs-2">
            <button type="button" class="btn btn-default" ng-click="submitPin()">Verify Pin</button>
        </div>
</form>

and the view:

class VerificationView(JSONResponseMixin, View):
    # other view methods

    @allowed_action
    def process_something(self, in_data):
        # process input data
        out_data = {
            'foo': 'bar',
            'success': True,
        }
        return out_data
