how to properly handle dom ready for Meteor

I am currently using iron-router and this is my very first attempt to try out the Meteor platform. I has been running into issues where most of the jquery libraries failed to initialized properly because the of the way Meteor renders html, $(document).ready() fires before any templates are rendered. I am wondering is there any callbacks from Meteor/iron-router that allows me to replace the jQuery's dom ready?

Also, how should I (easily and properly) handle the live update of the dom elements if some of them are customized by jQuery/javascript?

This is what i am currently doing, i feel like it is very hackish and probably would run into issues if the elements got updated after the initialization.

var jsInitalized = false;

Router.map(function () {
  this.route('', {
    path: '/',
    layoutTemplate: 'default',
    after: function(){
      if(!jsInitalized){
        setTimeout(function(){
          $(document).ready( function() { $$$(); });
        }, 0);
        jsInitalized = true;
      }
    }
  });
}
