MDL Table - Sortable property has no effect

[jirungaray]

I've setup a table according to the site:
public tableModel = new MdlDefaultTableModel([
{key:'material', name:'Material', sortable:true},
{key:'quantity', name:'Quantity', sortable:true, numeric:true},
{key:'unitPrice', name:'Unit price', numeric:true}
]);

but nothing seems to indicate sorting by that column is possible, Am I missing something?

need to remove the sorting property. it is not supported.
