title: Ext js Updating the total count of a paging toolbar on the fly
body: <p>This should be fairly simple but I haven't found a way to do it yet.</p>
  
  <p>I am using a ExtJs v.3.3.</p>
  
  <p>I have a grid panel that allows record deletion with context menu.</p>
  
  <p>The grid has a paging toolbar that is attached to the panel store.</p>
  
  <p>The deletion process sends an ajax request to the server, on success I remove the record from the store (using the remove method).</p>
  
  <p>The thing is that the paging toolbar does not reflect the change in the store , that is the total amount of records is unchanged until the store is reloaded.</p>
  
  <p>Is there any way to set the total amount of records in the paging toolbar?</p>
  
  <p>Thanks</p>
