$cordovaContacts returns nothing

I’ve tried to implement cordova contacts directly in my controllers and a service but never get either a success or error callback triggered.

If I try:

var options = {};
options.multiple = true;
console.log(JSON.stringify($cordovaContacts.find(options)));

I get:

 {"$$state":{"status":0}}

I’m not sure what this is related to and any pointers would be appreciated.
