How to specify a callback function for the CellSelectionCallback property for runtime created Tables in App Designer?

In App Designer:
Suppose that a TabGroup is created in App Designer's Design View, and that new tabs are simply added at runtime:
hTab = uitab(app.TabGroup,'Title',name_string);
Then suppose that a table is created as a child of the new tab, with a function specified for the CellSelection callback:
hTable = uitable(hTab,'CellSelectionCallback',@TableCellSelection);
The function TableCellSelection(app,event) is a private method in the app.
When the user selects some region of a successfully populated table, the following error results:
Undefined function 'TableCellSelection' for input arguments of type 'matlab.ui.control.table'.
Am I using an incorrect approach, or is this possibly a bug? Thanks.

MrToad,
It seems like MATLAB cannot locate the function. You could call the function from outside the app. Please see the app and script attached.
In the example attached, I called the function with app as an input:
hTable = uitable(hTab,'CellSelectionCallback',{@TableCellSelection app});
To test to see if the function works, I had it make a label visible.
function TableCellSelection(table_handle,events,app)
app.CellSelectionworksLabel.Visible = "on";
end
