Formspecs set this way do not trigger callbacks.
This method really only works for inventories.
Use on_rightclick and minetest.show_formspec if you want callbacks.
Formspecs set this way do not trigger the same callback. In order to
receive form input for meta formspecs, you must include an
`on_receive_fields` entry when registering the node.
This style of callback can trigger the callback when you press enter
in a field, which is impossible with `minetest.show_formspec`,
however, this kind of form can only be shown by right-clicking on a
node. It cannot be triggered programmatically.
*Note: node meta data will have been explained by this point in the full book*
