No hook (i.e. none of selected, autocomplete or cursorchange fired) if user types in exact match

I have bloodhound configured to fetch Json data, which it does very nicely.

   // constructs the suggestion engine

    var bloodHound = new Bloodhound({

        datumTokenizer: Bloodhound.tokenizers.whitespace,

        queryTokenizer: Bloodhound.tokenizers.whitespace,

        remote: {

            url: 'http://localhost:9000/invoices%QUERY',

            wildcard: '%QUERY'

        }

    });

In addition, the three main custom events are bound to the function "handler".

    ta.bind("typeahead:cursorchange", handler);

    ta.bind("typeahead:autocomplete", handler);

    ta.bind("typeahead:select", handler);

So almost everything works: if the user types in a string that matches part of a result and completes using tab, the autocomplete event fires and the correct item is selected. If the user uses the arrow keys or the mouse to select from the dropdown, that works. Even if the user types in the whole string matching a result but in the wrong case, and then presses tab, it works. BUT if the user types in a string that precisely matches the result, no event is fired and there is no direct way that I can find to get the data from the matching Json result into the form. I think this is a bug.
