problem with this.$el in backbone.js

test

#in the container
layout = Backbone.View.extend({
  el:"body"
  initialize: ->
    this.template = template.layout
    this.navigation = new navigation()
    this.render()
  render:->
    opt=
      container: config.option.container
    res = Mustache.compile this.template
    
    this.$el.empty()
    this.$el.append res opt
    this.navigation.render()
    this
});

#in the navigation:
navigation = Backbone.View.extend({
  el:"#navigation"
  initialize:->
    this.template = template.navigation
  render:->
    ###
    opt=
      option: config.option
      content:
        label:
          menue: interpreter.get "menue" 
          views: interpreter.get "views"
          uploadFiles: interpreter.get "uploadFiles"
          preview: interpreter.get "preview"
          details: interpreter.get "details"
          dirView: interpreter.get "dirView"
          process: interpreter.get "process"
    res = Mustache.compile this.template
    ###
    this.$el.empty()
    this.$el.append "<h1>Testing<h1>"
    #$("#navigation").append "<h1>Testing<h1>"
    this
})

#the template:
<div id="{{container}}" class="wrapper">
  <div id="navigation"></div>
  <div id="browser"></div>
  <div id="filter"></div>
</div>

its solved, i can`t instantiate the views of the inner parts before the outer ones are rendered
