Find by establishment and not by street GOOGLE MAPS

I'm using the following code to find streets in google maps, but I have the need to find establishments, here follows the link of the project, having difficulty finding the places.

var geocoder;
var map;
var marker; function initialize() {
    var latlng = new google.maps.LatLng(-18.8800397, -47.05878999999999);
    var options = {
        zoom: 5,
        center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP };
    map = new google.maps.Map(document.getElementById("mapa"), options);

geocoder = new google.maps.Geocoder();

marker = new google.maps.Marker({
    map: map,
    draggable: true,
});

marker.setPosition(latlng);}$(document).ready(function () { initialize();

function carregarNoMapa(endereco) {
    geocoder.geocode({ 'address': endereco + ', Brasil', 'region': 'BR' }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            if (results[0]) {
                var latitude = results[0].geometry.location.lat();
                var longitude = results[0].geometry.location.lng();

                $('#txtEndereco').val(results[0].formatted_address);
                $('#txtLatitude').val(latitude);
                $('#txtLongitude').val(longitude);

                var location = new google.maps.LatLng(latitude, longitude);
                marker.setPosition(location);
                map.setCenter(location);
                map.setZoom(16);
            }
        }
    })
}

$("#btnEndereco").click(function() {
    if($(this).val() != "")
        carregarNoMapa($("#txtEndereco").val());
})

$("#txtEndereco").blur(function() {
    if($(this).val() != "")
        carregarNoMapa($(this).val());
})

google.maps.event.addListener(marker, 'drag', function () {
    geocoder.geocode({ 'latLng': marker.getPosition() }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            if (results[0]) {  
                $('#txtEndereco').val(results[0].formatted_address);
                $('#txtLatitude').val(marker.getPosition().lat());
                $('#txtLongitude').val(marker.getPosition().lng());
            }
        }
    });
});

$("#txtEndereco").autocomplete({
    source: function (request, response) {
        geocoder.geocode({ 'address': request.term + ', Brasil', 'region': 'BR' }, function (results, status) {
            response($.map(results, function (item) {
                return {
                    label: item.formatted_address,
                    value: item.formatted_address,
                    latitude: item.geometry.location.lat(),
                    longitude: item.geometry.location.lng()
                }
            }));
        })
    },
    select: function (event, ui) {
        $("#txtLatitude").val(ui.item.latitude);
        $("#txtLongitude").val(ui.item.longitude);
        var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
        marker.setPosition(location);
        map.setCenter(location);
        map.setZoom(16);
    }
});

$("form").submit(function(event) {
    event.preventDefault();

    var endereco = $("#txtEndereco").val();
    var latitude = $("#txtLatitude").val();
    var longitude = $("#txtLongitude").val();

    alert("Endereço: " + endereco + "\nLatitude: " + latitude + "\nLongitude: " + longitude);
}); });
