I use a bootbox dialog to ask for the text and bindTooltip to leave the text.

map.on(L.Draw.Event.CREATED, function(e) {
    var layer = e.layer;
    bootbox.prompt({title: "Any comment?", closeButton: false, callback: putTooltip});
        function putTooltip(result) {
            layer.bindTooltip(result, {'permanent': true, 'interactive': true});
            }
    });

Try using L.Tooltip with permanent set to true.

From the Leaflet.Draw github, this code snippet works with a popup:

map.on(L.Draw.Event.CREATED, function (e) {
    var type = e.layerType,
        layer = e.layer;

    if (type === 'marker') {
        layer.bindPopup('A popup!');
    }

    editableLayers.addLayer(layer);
});

You can modify that code snippet to add a tooltip instead.
