Retrieve MySQL insert id in Meteor method

I am relatively new to Node and Meteor and am trying to retrieve the insert ID of a MySQL query using the numtal:mysql package. The trouble I run into is the query function running on the server and not returning to the client. I need the ID to return to the client so I can route the client to the newly created entry.

Client:

Template.new.events({
  'click .button.submit' : function(){
    Meteor.call('demoFunc', function(error, result){
      console.log(result);
    });
  },
});

Server:

Meteor.methods({
  demoFunc:function(){
    //construct deal object
    var newDeal = {
      dealer_id : 1,
      client_id : 1
    };

    //deal query
    liveDb.db.query('INSERT INTO deal SET ?', newDeal, function(err, result){
      return result.returnId;
    });
  }

});

If I could get the result.returnId in the demoFunc method to return to the client then I would be golden. If anyone's run into anything like this or worked around this, any help would be greatly appreciated.
