I'm not quite sure how or where to dig at all, but here is what I found
out after some (separated) testing:

works: 
GdaDataModel* gdadm = data_model->gobj();
std::cout <<
gda_value_stringify(const_cast<GdaValue*>(gda_data_model_get_value_at(gdadm,1,0))) << std::endl;

doesnt work:
std::cout << gda_data_model_get_n_rows(gdadm) << std::endl;

doesnt work either:
std::cout << data_model->get_value_at(1, 0).to_string();

I'll try anything you suggest, thanks for your patience,
 Daniel
