custom view detail meeting / document not same behaviour

[item]

Hi,
I have custom detail.js for meeting and document with same logic :

if (!~['Basic'].indexOf(this.model.get('type'))) {

                if (this.getAcl().checkModel(this.model, 'edit')) {
                    this.menu.buttons.push({
                            'label': 'journal',
                            'action': 'getJournal',
                            'style': 'default',
                            'iconHtml': '',
                            'acl': 'edit',
                   });

                    this.menu.buttons.push({
                            'label': 'xlsx',
                            'action': 'getXlsx',
                            'style': 'default',
                            'iconHtml': '',
                            'acl': 'edit',
                   });
                }

                this.listenTo(this.model, 'sync', function () {
                        if (~['Basic'].indexOf(this.model.get('type'))) {
                            this.$el.find('[data-action="getJournal"]').remove();
                            this.$el.find('[data-action="getXlsx"]').remove();
                        }

                }, this);
            } 

For Meeting, that's work perfectly, for Document, I need to refresh page or navigate next/previous record.
I have juste to precise I have documentFolder and each document is on the appropriate folder. I suspect this.
Another constatation, ".remove()" don't work on document, I have change it to .addClass('disable')

Juste another question : why I have loose the default "Send Invitations" button ? I do something wrong ?

Espo.define('custom:views/meeting/detail', ['crm:views/meeting/detail'], function (Dep) {

return Dep.extend({
    setup: function () {
        Dep.prototype.setup.call(this); 

Thanks in advance
