UIInput on mobile does not fire OnSubmit first time

[niniane]

I'm using an UIInput NGUI widget on iPhone.  The first time I press my button, edit the text using TouchScreenKeyboard, and press "Done", there is no "OnSubmit" fired.  When I open the edit box again, the text has reverted back to its original values.

The second and subsequent times that I press the button and edit the text, I do get "OnSubmit" fired, and my text changes stay applied.  Is this a known issue?

How can I get the OnSubmit to fire the first time also?

No, I haven't heard of this before. OnSubmit is always fired, unless the keyboard is closed instead of submitting. You can add some NGUIDebug.Log statements to the UIInput script where the keyboard gets closed (in the Update function) to make sure it happens.
