As I know the external list has about 25 limitations, because the data is stored into external data base. In your case you faced with these limitations:

  1. Workflows cannot be attached
  2. You cannot attach event receiver

In this post you can read

A workaround seems to be to create the external content type in Visual Studio. That way you can add some code to the create method to do additional things.

but I have not find any examples. I found out that in SharePoint 2013 you can use app to solve this issue. See this post for more details.
