How to capture a textchanged event when the textbox is inside a ListView?

I have a series of textbox in a listview which contain the hours and minutes for employees. I want values entered to be computed when any of the textboxes loses focus. I've tried this exemple from the MSDM. For button and LinkButton, I can use OnItemCommand, for DDl and listbox, I can use OnSelectedIndexChanged.

How about Textchanged for my texboxes? I don't see any event for them. From MSDN, the only method that resemble to that is TextBox.TextChanged Event. But it said on that page : "This API supports the .NET Framework infrastructure and is not intended to be used directly from your code."

The TextBoxes are in the ItemTemplate(or EditItemTemplate), aren't they? If they have AutoPostBack=true they'll post back as soon as the text changed and the focus lost. Just the same as outside of a ListView.

on aspx:

<ItemTemplate>
  <tr runat="server">
    <td>
      <asp:TextBox OnTextChanged="TextBox1_TextChanged" AutoPostBack="true"
            ID="Textbox1" runat="Server" Text="here is text"  />
    </td>
    <td>
  </tr>
</ItemTemplate>

in codebehind:

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
   TextBox TextBox1 = (TextBox) sender;
}
