Callback on 'save' on 'new node form' doesn't fire
You would be better off using hook_node_submit which would fire when any node is submitted.

You can make it specific to your node by the following:

function MODULE_node_submit($node, $form, &amp;$form_state)
{
    if ($node-&gt;type == "NODE-TYPE")
    {
        //do stuff
    }
}
