Table - Column set as number or date

Hi,

Following this example : SAPUI5 SDK - Demo Kit

My table has the following fields:

- ID (number)

- Name

- Date

The sort does not work with ID or Date.

Could you

oTable.addColumn(new sap.ui.table.Column({    label: new sap.ui.commons.Label({text: "id"}),    template: new sap.ui.commons.TextView().bindProperty("text", "id"),    sortProperty: "id",    filterProperty: "id",    width: "100px"
}));

How can I set column as number or date ?

Thank you,

Philippe
