No progress happening

Button doens't fill when I hook it into my service. Currently using:

```
$scope.change = function() {
$scope.loader = NodeFactory.update({ id: $scope.newentry.nid }, $scope.data);
$scope.loader.$promise.then(function () {
//$state.go('start', {'id': $scope.newentry.nid});
});
};
```

With my button set as:

```
Save & Continue
```

The server is taking about 10sec to resolve the promise, the button doesnt fill and simply flips to the done animation.
