How to use PREDICT in an app?

[gcor71]

I have trained a model to predict the "scout group" based on an structured input text string. eg: 
INPUT column NOTE: "Enter ticket holder full name (person attending): John Doe | Enter Group & Section (ie 99th Portsmouth, Cubs): 70th Portsmouth squirrels".
OUTPUT column GROUP: "70th Portsmouth".
This is a table called TRAINING_DATA and the prediction is 100% when adding a new row to this table(!).

The problem I have is moving away from the TRAINING_DATA table and trying to apply the PREDICT("group") in my live data, which is a second table called ORDERS.  ORDERS has a NOTE column and a GROUP column.  I have variously set the GROUP column to have PREDICT("group") in the Initial Value or the Formula settings for the column.  But, nothing happens when I add a new row in the ORDERS table which includes a NOTE.

I had anticipated that the GROUP column in the ORDER table would update - using NOTE against the predictive model.  It does not.

How should I approach this?
