First, a dataProvider should contain data. It looks like you are putting ui components in the dataProvider. Unless you are working a very extreme edge-case, you do not want to do that. What are you trying to accomplish?
Second, you cannot use creationComplete to show row/item level UI in a renderer. All display work in a renderer must happen as the result of the framework's call to the set data() function. Typically, one overrides set data(). I think you may have some basic misconceptions to work through.

I have a datagrid that uses a item renderer. The main app is defined like in the first part of the attached code. The itemrenderer looks like the second part of the attached code. When I run it, the first item of my dataprovider is not shown while the first line of my datagrid is always empty... Any idea to explain this strange behavior ? Thanks in advance...
