TextChanged / LostFocus / etc .. event for DataGridTextColumn

Question

I have a list of objects attached to DataGridon a WPF page, and I want to add an object immediately after the current one, if the value entered in a specific column is less than a certain number.

<my:DataGridTextColumn Binding="{Binding Path=Hours}"/>

I can’t understand for life how to associate an event with a base one TextBox. Various sites cite the ability to do this, but none of them provide related code. At the moment I am using DataGridTemplateColumnc TextBoxinside it, but it seems to me that I cannot get the current line with this solution.
