Why dont you make it a link style it to appear like a button which points to the needed page with query string of the employee id. And if need add this attribute to the link target='_blank'
Something like this
+"<td><a id=''+ data.d[i].EmpId + '' src='EmployeeEdit.aspx?id=" + data.d[i].EmpId +' target='_blank'>Edit</a></td>"
+"<td><a id=''+ data.d[i].EmpId + '' src='EmployeeView.aspx?id=" + data.d[i].EmpId +' target='_blank'>View</a></td>"
