title: Add multiple objects into one object
body: <p>How can I add multiple objects into one object? I have a selectbox change event that has a handler like this:</p>
  
  <pre><code>this.selectBoxChanges = {};
  
  onSelect: function(event){
      var p = $(event.currentTarget).attr('id');
      var obj = {};
      obj[p] = $(event.currentTarget).val();
      this.selectBoxChanges = obj;
  },
  </code></pre>
  
  <p>What I wanted to do is store all my objects in an object called <code>selectBoxChanges</code> so that when a confirm button is selected all the objects will be passed to a backbone model. Like this:</p>
  
  <pre><code>onConfirm: function(){
      this.model.set(this.selectBoxChanges);
  }
  </code></pre>
