It's not there that you must do something. It's before.
Don't use gtk_text_buffer_set_text(). That will overwrite everything in
the text view with it's argument.
Use gtk_text_buffer_insert(). Get and end iter with
gtk_text_buffer_get_end_iter().
You should really look at the documentation for GtkTextView and its
associated classes.
