Is there a way to sort on a hidden column instead to the visible column?

I need to sort on a datetime with a specific format but it doesn't work as it's a string

thank

Hi Alexander,

I want to Sort a date column (which is displaying as string type) with value of other hidden column. As mentioned below

 LastCurDate: { type: "string" },
 dtLastCurDate: { type: "string" }

AND 
                    {
                        field: "dtLastCurDate", title: "Last Current", filterable: { multi: true, dataSource: [{ dtLastCurDate: 'Less than 14 days' }, { dtLastCurDate: 'Between 14 to 30 days' }, { dtLastCurDate: 'More than 30 days ago' }], checkAll: false }, sortable: true,
                        template: "<div class=\"displayInlineBlock\" style='width:140px;'>${LastCurrentDate}</div>"
                    },
