I have two methods setTheString and theString.
They return the value of another NSTextField on my window.
In IB I binded the value of the textField to App Controller and the

theString() is only called when the app first starts up.
Firstly, it's -theString, not theString().
What you are doing sounds like a big no-no in MVC design. It sounds to
me like your code does something like:
- (NSString *)theString
{
return [textField stringValue];
}
In which case, how on Earth is the binding supposed to know when the
result of that method has changed? It is not KVO compliant.
Instead, you want to create a perfectly *standard* accessor method for
the -theString and -setTheString: that returns an instance variable.
Then, bind both of your text fields to it. That will ensure proper KVO
compliance.
