I am adding the Button to Element as below.

```
(this.sample as any).element.addEventListener("mouseover", function (e) {
      if ((e.target as HTMLElement).classList.contains("e-rowcell")) {
        let ele: Element = e.target as Element;
        let row = parentsUntil(ele, "e-row");
        this.row = row;
        row.lastChild.appendChild(this.button);
        row.lastChild.appendChild(this.button1);
      }
    }.bind(this));

```
