code inspections for javascript vars in parent scope ?

We have a project using the titanium api with this little testsetup. Btw. we dont know exactly if this problem points to titanium api. 

app.js:

var services = {};
services.testvar = {
    value : 1
};

var test = require('test');
test_object = new test();

test.js:

module.exports = function() {
   services.testvar = 2;
};

and now we have the problem that in test.js code inspection says on services: element is not exported

is there a possibility to make services known for the ide or what can we do to use code inspections right?
