grid.appendTo('#Grid');

let btn: Button = new Button({ cssClass: 'e-flat' }, '#change-text');

document.getElementById('change-text').addEventListener('click', () => { // changing the header text for ShipCity column.
    let column: Column = grid.getColumnByField("ShipCity"); // get the JSON object of the column corresponding to the field name.
