DatetimePicker Format

I try to get this format when i select a date and an hour like : 04/04/2017 - 14:58

but actually with this form :

<div class="input-group date form_datetime">
                                    <div class="input-group-addon">
                                        <i class="fa fa-calendar"></i>
                                    </div>
                                    <input type="datetime" name="datetime" class="form-control pull-right">
                                </div><!-- /.input group -->

i get 04 April 2017 - 14:58

I don't know how to change this ! for info i use AdminLte for Laravel
