If im not mistake you should do this

    //Here you add event to button
    void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (e.Control is Button)
        {
            Button btn = e.Control as Button;
            btn.Click -= new EventHandler(btn_Click);
            btn.Click += new EventHandler(btn_Click);
        }
    }

    void btn_Click(object sender, EventArgs e)
    {
        if(sender is button)
            ((button)sender).Text = "new text";
    }

I hope this help

void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
            {
                if (e.Control is Button)
                {
                    Button btn = e.Control as Button;

                    // hook or unhook click event here
                }
            }
