Typeahead 0.10 prevent caching

I use twitter's typeahead 0.10 with remote url to retrieve JSON results from server.

I would like to prevent tthe client caching so that the search takes place always on the server. How can I do that?

Please see below my code:

 // instantiate the bloodhound suggestion engine
    var dataSource = new Bloodhound({
        datumTokenizer: function (d) {
            return Bloodhound.tokenizers.whitespace(d.value);
        },
        queryTokenizer: Bloodhound.tokenizers.whitespace,
        remote: {
            url: "../" + autocompleteInfo.ControllerName + "/" + autocompleteInfo.MethodName + "?term=%QUERY&ts=" + (new Date().getTime()),
            filter: function (res) {
                var data = [];
                data = $.map(res, function (item) {
                    return { label: item.Name, id: item.Id, autocompleteInfo: autocompleteInfo, cssClass: item.Class };
                });

                return data;
            }
        },
        limit: 15,
        name: 'typeaheadSourceCache',
        ttl: 0,
        ajax: {
            cache: false
        }
    });

    dataSource.initialize();

    $("#" + autocompleteInfo.AutocompleteId).typeahead({
        minLength: 3,
        highlight: true,
        autoselect: true
    },
        { 
            displayKey: 'label',
            source: dataSource.ttAdapter(),
            templates: {
                suggestion: Handlebars.compile(
                '<div class="searchItem {{cssClass}}">{{label}}</div>'
                )
            }
        });

Look at version 10.0.2. There is now a means to clear cache via Bloodhound.js (used in association with Typeahead.js):

engine.clearRemoteCache();

Here is the documentation from twitter typeahead: https://github.com/twitter/typeahead.js/blob/master/doc/bloodhound.md#bloodhoundclearremotecache
