      $(".ckeditor").each(function(){  CKEDITOR.replace('ckeditor1');} );
}

<apex:commandButton value="Add Product" action="{!AddProduct}" rerender="theForm" oncomplete="ReloadCKEditor();">
      <apex:param name="ProductIndex" value="{!G.Index}"/>                                                        
</apex:commandButton>

<apex:column breakBefore="true" colspan="5">
