title: Sencha touch 2.2 sql proxy not inserting data
body: <p>I successfully tried sencha touch app example showed <a href="http://miamicoder.com/2012/how-to-create-a-sencha-touch-2-app-part-4/" rel="nofollow noreferrer">here</a>  </p>
  
  <p>They are using store proxy type as <strong>localstorage</strong>, its working good and then i changed the proxy type to sql as shown below </p>
  
  <pre><code>Ext.define('notesApp.store.Notes', {
      extend : 'Ext.data.Store',
      requires : 'Ext.data.proxy.Sql',
      config : {
          model : 'notesApp.model.Note',
          proxy : {
              type : 'sql',
              database: "SqlProxyTest",
              table: "Notes",
              id : 'notes-app-store'
          },
          sorters : [{property : 'dateCreated', direction : 'DESC'}],
          grouper : {
              sortProperty : 'dateCreated',
              direction : 'DESC',
              groupFn : function(record) {
                  if(record &amp;&amp; record.data.dateCreated) {
                      return record.data.dateCreated.toString();
                  }
                  return '';
              }
          }
      }
  });
  </code></pre>
  
  <p>There is no error.
  I can insert data and i can see the record in list view, but chrome resource showing "The Node table is empty".
  If i refresh the browser the record is gone from the list.</p>
