Keep Bootstrap-datetimepicker always open also when hitting key enter

Question

I'm using Eonasdan bootstrap date/timepicker. I want my calendar is always shown, even if I press enter key in the input field. So far I managed showing always open the calendar except when hitting enter key by using attributes:

keepOpen: true, 
inline: true, 
debug: true.

Segment of JS code

$(function () {

            $('#datepicker').datetimepicker({
              format: 'DD.MM.YYYY',
              keepOpen: true,
              inline: true,
              debug: true,
              icons:{
                    date: 'fa fa-calendar',
                    up: 'fa fa-chevron-up',
                    down: 'fa fa-chevron-down',
                    previous: 'fa fa-chevron-left',
                    next: 'fa fa-chevron-right',
                    today: 'fa fa-screenshot',
                    clear: 'fa fa-trash',
                    close: 'fa fa-remove'
                }
               //beforeShowDay: 

                    // daysOfWeekDisabled: [0,6]



            });

Segment of html code:

<div class="input-group date" data-provide="datepicker"> 

    <input  id="datepicker" type="text" name="date" class="form-control input-md">

    <div class="input-group-addon dt-cal">

        <span class="fa fa-calendar"></span>

    </div>

</div>

You need to use:

keyBinds(): allows for custom events to fire on keyboard press.

The default value for enter key is:

enter: function () {
    this.hide();  // exactly what you don't want...
},

It is enough to remove such default behavior:

$('#datepicker').data("DateTimePicker").keyBinds({'enter': null});

$('#datepicker').datetimepicker({
    format: 'DD.MM.YYYY',
    keepOpen: true,
    inline: true,
    debug: true,
    icons:{
        date: 'fa fa-calendar',
        up: 'fa fa-chevron-up',
        down: 'fa fa-chevron-down',
        previous: 'fa fa-chevron-left',
        next: 'fa fa-chevron-right',
        today: 'fa fa-screenshot',
        clear: 'fa fa-trash',
        close: 'fa fa-remove'
    }
    //beforeShowDay:
    // daysOfWeekDisabled: [0,6]
});
$('#datepicker').data("DateTimePicker").keyBinds({'enter': null});
