title: Bootstrap Typeahead and Tagsinput doesn't live together
body: <p>i made this script and works perfectly:</p>
  
  <pre><code>$('.js_tags').typeahead({
              minLength: 3,
              source: function (query, process) {
                  return $.ajax ({
                      url: '/app/route',
                      type: 'POST',
                      data: 'query='+query,
                      dataType: "json",
                      async: true,
                      success: function (data){
                          process(data);
                      },
                      error: function (request, status, error) {
                          console.log(request.responseText);
                      }
                  })
              }
          });
