Answer 1

You are wrapping the wrong function here, Meteor.wrapAsync transforms an async function (this means a function which transmits its result to the caller via a callback) in a synchronous one.

The function you pass to Meteor.wrapAsync does not have a callback as final argument, you should instead wrap _stripe.charge.create.

stripe.charge = function (stripeToken) {
  var _stripe = StripeAPI(stripeToken);
  var stripeChargeSync = Meteor.wrapAsync(_stripe.charge.create,_.stripe.charge);
  var response = stripeChargeSync({
    amount: 1000, // amount in cents, again
    currency: "cad",
    card: stripeToken.id,
    description: "paid@whatever"
  });
  return response;
};

If you want to handle errors, you should use a try/catch block when calling stripe.charge.

try{
  stripe.charge(STRIPE_TOKEN);
}
catch(exception){
  console.log("Sorry we couldn't charge the money",exception);
}

I see you are logging your error using alert, are you trying to use Meteor.wrapAsync on the client ? Meteor.wrapAsync is meant to be used on the server because the environment needed to provide synchronous-looking execution is available in Node.js, not the browser.
