Programmatically select the first suggestion in django-autocomplete-light

Question

How can I select the first given option? I'm feeding the autocomplete widget with the data from reverse geocoding results (city) basing on user's location. I have a database with cities and I need to select the first suggested option.

autocomplete_light_registry.py

autocomplete_light.register(
    City,
    search_fields=('^name',),
    autocomplete_js_attributes={'placeholder': _('Start typing...')}
)

forms.py

class CustomerForm(forms.ModelForm):
    city = forms.ModelChoiceField(City.objects.all(), label=_('City'), widget=autocomplete_light.ChoiceWidget('CityAutocomplete'))

locations.js

$('#id_city_text').val(ymaps.geolocation.city);
var autocomplete = $('#id_city_text').yourlabsAutocomplete();
autocomplete.refresh();

Thanks for your help.

Here's how to auto select the first choice if there is only one:

        $(document).ready(function() {
            var autocomplete = $('#id_city_text').yourlabsAutocomplete();
            autocomplete.show = function(html) {
                yourlabs.Autocomplete.prototype.show.call(this, html)
                var choices = this.box.find(this.choiceSelector);

                if (choices.length == 1) {
                    this.input.trigger('selectChoice', [choices, this]);
                }
            }
        });
