[c#] Dinamically ImageButton in code behind

[sersul]

Sto creando un ImageButton dinamicamente in questo modo:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack) {
            ImageButton ib = new ImageButton();
            ib.ID = "IBIDLJKK";
            ib.ImageUrl = "../../App_Themes/White/Images/button-delete.gif";
            ib.CommandName = "ib_Command";
            ib.Click +=new ImageClickEventHandler(ib_Click);
            Control c = FindControl("form1");
            c.Controls.Add(ib);
        }
    }

ma l'evento ib_click non mi viene catturato.

Qualche aiuto?

Thanks

    protected void Page_Load(object sender, EventArgs e)
    {
        ImageButton ib = new ImageButton();
        ib.ID = "IBIDLJKK";
        ib.ImageUrl = "../../App_Themes/White/Images/button-delete.gif";
        ib.CommandName = "ib_Command";
        ib.Click += new ImageClickEventHandler(ImageButton_click);
        this.Form.Controls.Add(ib);

    }

    protected void ImageButton_click(object sender, ImageClickEventArgs e)
    {
        this.Response.Write(DateTime.Now);
    }
