It didn't came to my mind i had to sort the model, not the treeview 
column. Probably because I was already using this code for the user 
clickable headers:

m_treeview.get_column(idx)->set_sort_column(m_column.xxxx);

But this requires user interaction (clicking on the header) to perform 
the sort. However, the function with the same name for the treestore 
sorts immediately. Thanks!
