It's set by gtk_tree_view_column_add_attribute(..., "text", X) call

Doc: http://library.gnome.org/devel/gtk/stable/GtkTreeViewColumn.html#gtk-tree-view-column-add-attribute
"So for example if column 2 of the model contains strings, you could
have the "text" attribute of a GtkCellRendererText get its values from
