title: ExtJs - How to trigger the update event on a store manually?
body: <p>How to fire the <code>update</code> event on a store manually, by clicking a button or a link?</p>
  
  <p>I'm trying this:</p>
  
  <pre><code>var someStore = Ext.getCmp('someGrid').getStore();
  //Save yes is a hyperlink I inserted in the DOM.
  
  Ext.get('save-yes').on('click', function(e){
      e.preventDefault();
      someStore.fireEvent('update');
  });
  
  someStore.on('update', function(){
      console.log('Updating');    
  });
  </code></pre>
  
  <p>The click works, but the store's event is not triggered.</p>
