GetContent fired twice

[Colir]

Hi, i've noticed a stange behavior

when puttin a console.log on the 'getContent' this event is fired twice or more time...

I'm looking for a way to have thie event fired only one time...any idea ?

    public function admin_print_footer_scripts() {
        if ( ! isset( get_current_screen()->id ) || get_current_screen()->base != 'post' )
            return;
        ?>
        <script type="text/javascript">
            (function($){
                var media = wp.media, shortcode_string = 'boutique_banner';
                wp.mce = wp.mce || {};
                wp.mce.boutique_banner = {
                    shortcode_data: {},
                    template: media.template( 'editor-boutique-banner' ),
                    getContent: function() {
                        console.log('getContent')
                            var options = this.shortcode.attrs.named;
                            options['innercontent'] = this.shortcode.content;
                            return this.template(options);
                        },
                    View: {
                        // before WP 4.2:
                        template: media.template( 'editor-boutique-banner' ),
                        ...
