Answer 1

you need to bind your input to the onchange action

Use this

$(document).ready(function(){
    $("#typeahead").change(function(event){
        var query = document.getElementById('typeahead').value;
        jQuery.ajax({
            url: 'autocomplete.php',
            type:'POST',
            data:{'query':query},
            dataType: 'JSON',
            cache:false,
            success:function(data){
                // Do Anything You want here
            },
            error:function(){
                // Do something else here
            }
        });
    });
});
