Is there any option to init (text/x-magento-init) script after page load? Example, I am working on a simple quickview feature and my controller returns my a layout - phtml file - with rendered html and script with config like this below:

<script type="text/x-magento-init">
    "[data-role=swatch-options]": {
        "Magento_Swatches/js/swatch-renderer": {
            "jsonConfig": ...

New content is appended to modal wrapper and new popup is initialized. Is there any option to fire (maybe some kind of event od body/document) which triggers again init process for Magento_Swatches/js/swatch-renderer script?

  • Did you get to the bottom of how to do this. I need to initialise swatches on ajax loaded product list as not working with infinite scrolls so may be similar?

I believe you need to use .trigger('contentUpdated') When you get the Ajax Content trigger the contentUpdated event so the new data-mage-init to be evaluated. e.g.

var contentBlock = this.element.find('.page-footer');
        url: this.options.contentsUrl,
        type: 'GET',
        dataType: 'html',
        data: {
            'form_key': FORM_KEY,
            node: node.id
        context: contentBlock,
        showLoader: true
    }).done(function (data) {
