Mohon bantuan gan yang bisa flexigrid,

ane lagi bikin tabel pake flexigrid, cuma fungsi "onpress" kalo ane masukin flexi grid jadi nggak muncul. Kira-kira kalo mau menjalankan fungsi button ada cara lain nggak?

buttons : [
{name: 'Add', bclass: 'add', onpress: dosomething},
{name: 'Delete', bclass: 'delete'},
{separator: true}
],
