Textbox Data Binding in VS 2008, Works on a Main form but not in a Dialog!

Question

I got a perplexing problem here with Databindings. I'm using a POCO class for XML serialization that implements the INotifyPropertyChanged. I'm using Visual Basic 2008 and unfortunately I have to keep the program that way!
I have two projects: One is a Main WinForm, and the other one I'm working with another engineer and I'm trying to create a dialogbox for the users to enter in data (ie: user name, calibration data, etc)
In my Main Winform, I'm doing databinding like this:
TextBoxUserName.DataBindings.Add("Text", data, "Name", False, DataSourceUpdateMode.OnPropertyChanged)
And it works fine, but when I do this in the dialogbox form, NOTHING is being updated. Not the textbox nor the data.name member (which is also a string)
So what's the problem then? How come it works in the instance of the Main Winform but not in the dialogbox?
