Add google analytics trackevent to angular code

I have a small application written in Angular using CoffeeScript for JavaScript and CoffeeKup (for template files).

I need to 1) add google tracking code to the page and 2) add a google tracking event to a form submit, but I have poor knowledge of Angular. Can you do it for me?

I think this is the section I need to add the _trackevent code, but I can send you the project files if you need more context

return $scope.onSubmitRequest = function() {
console.log('Submit request for: ' + $scope.userRequest.name + ' ' + $scope.userRequest.country);
Meteor.call('createCase', $scope.userRequest, basketService.items);
basketService.items.length = 0;
basketService.saveItems();
return $location.path('/request-complete');
};
