Is it possible to fire a call for multiples of 3 in typeahead.js

typeahead.js jQuery plugin fires call for every letter or we can give the minLength for suggestions rendering. I want to show the suggestions only for multiples of 3

$('#the-basics .typeahead').typeahead({
                hint: true,
                highlight: true,
                minLength: 3
            },
                {
                    name: 'items',
                    source: substringMatcher(items)
                });
