How to access composite control using javascript in RadDataForm

[T]

I have a composite control that has a link button and RadAyncUpload in RadDataForm.
I access the control as follows using Javascript in a  WebForm.

var filelength = find("<%= CompositeControl1.RadAsyncUpload.ClientID %>").getUploadedFiles().length;

I am not sure how to access this control using javascript from RadDataForm.

I tried using the following,

 var container = $(".RadDataForm")[0];
 var uploaded = $telerik.findElement(container, "CompositeControl1");

I am not sure how to access RadAsyncUpload from the above.Any help is appreciated.Thank you.
