Typeahead clears input when value is provided by javascript

Question

I’m using the Typeahead version 0.9.3 to auto-complete my inputs. It’s working fine, get the bank info and show it all right.

However, if I want to define some value for the input through Javascript. When the user clicks over the field and then out the value of the field is null.

If I put the value on the property value of input. This does not occur. My problem is that I need to assign value to the input through the Javascript.

$(document).ready(function() {
    $('#teste').typeahead({
        limit: 50,
        minLength: 1,
        remote : '../db/dbAutoComplete.php?&query=%QUERY'
    });

    $('#teste').val('Valor que some se clicar fora do campo');
    //Estou forçando o valor a título de exemplo

});

And My HTML has only input.

input type='text' name='teste' id='teste' value='' required
