How to use typeahead in multiple fields at the same time?

Hello, I wanted to know how I can be using typeahead on various inputs.

The problem is, typeahead only works on the first input, otherwise it does not work.

<input type="text" name="palavras" class="form-control typeahead" data-provide="typeahead">

var substringMatcher = function (strs) {
   return function findMatches(q, cb) {
      var matches, substrRegex;
      matches = [];
      substrRegex = new RegExp(q, 'i');
      $.each(strs, function (i, str) {
         if (substrRegex.test(str)) {
            matches.push(str);
         }
      });
      cb(matches);
   };
};

var palavras= ['olá', 'tudo bem', 'sol', 'praia','neve'];

$('.typeahead').typeahead({
   hint: true,
   highlight: true,
   minLength: 1
},{
  name: 'palavras',
  source: substringMatcher(palavras)
});

I hope to open a legal discussion on this topic.
