title: Ember Data Adaptor throws has no method 'updateRecord' even though updateRecord function is implemented?
body: <p>I am rolling my own adaptor for Ember data. Long story short, when I call App.store.updateRecord(App.Model, id ) I get this error:</p>
  
  <p><code>Uncaught TypeError: Object &lt;DS.Store:ember195&gt; has no method 'updateRecord'</code></p>
  
  <p>even though updateRecord function is implemented.</p>
  
  <p>Sample code below ( note for clarity sake, I had all the functions log parameters to console instead of doing what they are suppose to do )</p>
  
  <pre><code>// declare application namespace
  App = Ember.Application.create();
  
  // instantiate store
  App.store = DS.Store.create({
      revision: 2,
      adapter: DS.LocalStorageAdapter.create(),
  });
  
  // implement adapter
  DS.LocalStorageAdapter = DS.Adapter.extend({
  
    createRecord: function(store, type, model) {
      console.log('createRecord: ', type, model);
  
    },
  
  
    updateRecord: function(store, type, model) {
      console.log('updateRecord: ', type, model);
  
    },
  
    find: function(store, type, id) {
      console.log('find: ', type, id);
  
    },
  
    localStorage: {
      set: function( ModelTyp, value ){},
  
      get: function( ModelType ){},
    }
  
  });
  
  // create model
  App.StyleData = DS.Model.extend({
  
      css_name: DS.attr('string', {key: 'css_name'}),
      storageID: DS.attr('number', {defaultValue: 0, key: 'storageID'}),
  
  });
  
  // ==========================================================================
  // Test Application
  // ==========================================================================
  
  
  App.store.createRecord(App.StyleData, { css_name: 'name' });
  App.store.commit()   
  //console: createRecord:  App.StyleData, model
  
  App.store.find(App.StyleData, 0)   
  //console: find: App.StyleData, 0
  
  App.store.updateRecord(App.StyleData, { css_name: 'new name' });  
  //console: Uncaught TypeError: Object &lt;DS.Store:ember195&gt; has no method 'updateRecord' 
  </code></pre>
  
  <p>Pretty much at the end of my wits here since I can't figure out what is going on underneath the hood.</p>
