DateTimeControl OnDateChanged

[ElenXYZ]

Hi! I am using DateTimeControl in Page. I have some business logic on DateChanged event. My problem here is i am not getting the event when the time changes.

<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

protected void DateTimeControl1_OnDateChanged(object sender, EventArgs e)
{
Label1.Text = DateTimeControl1.SelectedDate.ToString();
}

Please, help me.
