Just include a callback with your Meteor.call. The callback will be run after the server has completed processing the request.

Template.task.events({
  'click .delete': function () {
    Meteor.call('deleteTask', this._id, function(err, result){
      if (err){
        // an error was thrown
      } else {
        // everything worked!
      }
    })
  }
});
