The table object is an array so to read you need to:

var teste = ca_fdGetInsertedTableRows(ca_fd.formId, 'permisos');
2. Alert with the format of variable[value].ID of the field.
Example:
alert("Valor "+teste[0].ruta+ " - ");
alert("Valor "+teste[0].List+ " - ");
alert("Valor "+teste[0].Read+ " - ");
