If statement doesn't seem to work

Hi Metabox,

I've added the following MB view as a shortcode block:

     {{ post.online_evenement }}
        {% if '{{ post.online_evenement }}' != 1 %}
            <h3>Locatie {{ post.online_evenement }}</h3>
            <div class="locatie_gegevens">
                <div>
                    {{ post.naam_bedrijf }}
                </div>
                <div>
                    {{ post.straat }} {{ post.straat_nummer }}
                </div>
                <div>
                    {{ post.postcode }} {{ post.stad }}
                </div>
                <div>
                    {{ post.land }}
                </div>
            </div>
        
        {% endif %}

The field Post.online_evenement is a checkbox, so it has a value of 1 if checked and a value of zero if it is not checked. The MB view displays the value when rendered, but it also displays the content between the if statement, no matter if the field is checked or unchecked. See the following screen recording: https://share.getcloudapp.com/4gu22RmY

What am I doing wrong in the if-statement? Can you help me?

Kind regards, Henri
