Use your columns renderer function as follows:

{
                id       :'data',
                header   : 'Data', 
                width    : 160, 
                sortable : true, 
                dataIndex: 'data',
                renderer : function(value, metadata,record) {
                    return setTooltip(value, metadata,record);
                }
            }


    function setTooltip(value, metaData, record){
        var deviceDetail = record.get('data') + ": " + record.get('description');
        metaData.attr='ext:qtip="' + deviceDetail + '"';
        console.log("deviceDetail: " + deviceDetail);
        return value;
    }
