    // Gjs wrapper for gtk_tree_view_insert_column_with_data_func()
}

Convenience function that inserts a new column into the Gtk.TreeView with the given cell renderer and a Gtk.TreeCellDataFunc to set cell renderer attributes (normally using data from the model). See also Gtk.set_cell_data_func, Gtk.pack_start. If tree_view has "fixed_height" mode enabled, then the new column will have its "sizing" property set to be GTK_TREE_VIEW_COLUMN_FIXED.

position: Position to insert, -1 for append
title: column title
cell: cell renderer for column
func: function to set attributes of cell renderer
Returns: number of columns in the tree view post-insert
