title: Ext.create returns constructor instead of object
body: <pre><code>Ext.application({
          name: 'test',
          launch: function() {
              var grid = Ext.create('Ext.grid.Panel', {
                  id:'grid',
                  renderTo: Ext.getBody(),
                  store: userStore,

                      },

                          text: 'word2',

                      }
                  ],
                  dockedItems: [
                      {

                          store: userStore,
                          dock: 'bottom',
                          displayInfo: true
                      }
                  ]
              });
  
              //error here
              grid.reload();
  </code></pre>
  
  <p>I see error in console:</p>
  
  <blockquote>
    <p>Uncaught TypeError: Object [object Object] has no method 'reload'</p>
  </blockquote>
  
  <p>In debugger I see that variable 'grid' has type of 'constructor'</p>
  
  <blockquote>
    <p>grid:constructor</p>
  </blockquote>
  
  <p>So it's no wonder why there is no method 'reload'. It's wonder for me why I'm getting a reference to constructor function instead of reference to newly created object.</p>
  
  <p>The same problem occurs when instantiating another ExtJs core classes.</p>
  
  <p>May it somehow be related to my project structure?</p>
  
  <p>P.S. I'm new to JavaScript, so it will be no surprise for me if the problem is in my poor understanding of core concepts.</p>
