cannot test an Action that handles a promise

Hi there I Have an Action that handles a promise and I am having problems testing it

the action has a private method handleResponse() to load data asynchronously it also has a Service injected via a setService() action.

var handleResponse = function(promise) {
submissionsActions.onLoadSubmissions({
processing: true,
loading: false
});

```
// Only show the loading message if the response takes more than half a second
var loadingTimer = setTimeout(function() {
submissionsActions.onLoadSubmissions({
processing: true,
loading: true
});
}.bind(this), 500);

promise
.then(function(submissions) {
submissionsActions.initStore(submissions);
submissionsActions.onLoadSubmissionsSuccess(submissions);
}.bind(this))
["finally"](function() {
clearInterval(loadingTimer);
})
["catch"](function(error) {
try {
submissionsActions.onLoadSubmissionsFail(error);
} catch (ex) {
console.error(ex);
}
}.bind(this));
};
```

var submissionsActions = alt.createActions({
loadSubmissions: function() {
handleResponse.call(this, service.getSubmissions());
},
setService: function(ser) {
console.log('Submissions Actions setting service',ser);
service = ser;
},
});

On my test I am using Sinon to mock the service and its response to getSubmissions:

service = {
getSubmissions: function() {
console.log('IWAS CALLED');
return {"submissions": []};
},
refreshSubmissions: function() {}
};

```
Actions.dispatch = function() {};
Actions.setService(service);

defer = Q.defer();
defer.resolve({"submissions": []});
sinon.stub(service, 'getSubmissions').returns(defer.promise);
Actions.loadSubmissions();

// Push Q
this.clock.tick();
```

when the promise is fulfilled: i.e
.then(function(submissions) {

I am getting the below error:
Uncaught ReferenceError: submissions is not defined
at AltAction.eval (eval at evaluate (unknown source), :1:1)
at Object.InjectedScript._evaluateOn (:895:55)
at Object.InjectedScript._evaluateAndWrap (:828:34)
at Object.InjectedScript.evaluateOnCallFrame (:954:21)
at AltAction.handleResponse

It seems that AltAction.eval() is ignoring the resolved promise.

Any help would be greatly appreciated.
