Take a look at http://scm.bluequartz.net/mxa/mxadatamodel/trees/master/Code/MXA/DataImport for an example of how I did this in one of my older projects.

The code that ties this together is then in http://scm.bluequartz.net/mxa/mxadatamodel/blobs/master/Examples/DataImport/main.cpp

This should short enough for you to follow along. I am not saying mine is the utopian example but it does work.
