Dropzone.js - Error: Invalid `clickable` option provided

Question

I'm using dropbox.js and I get this error: Error: Invalid clickable option provided . I've tried all solutions possible about the clickable option.

1. clickable: "#add-new",
2. clickable: '#add-new',
3. clickable: ['#add-new'],
4. clickable: ["#add-new"],

I've updated my version but still I don't know how to fix it. My objective is to append a button on each added element (previewTemplate) for adding new elements further.

Is there any workaround to fix this or another solution? Thanks.

var myDropzone = new Dropzone('div#myDropzoneElement2', {
        maxThumbnailFilesize: 2,
        maxFilesize: 2,
        acceptedFiles:'image/*',
        clickable: ["#add-new"],
        thumbnailWidth: 250,
        thumbnailHeight: 125,
        url: dropzoneUrl,
        previewTemplate: "<div class=\"dz-preview dz-file-preview col-sm-12\">\n  <div class=\"row\"><div class=\"col-sm-5 col-md-4\"><div class=\"dz-image\"><img data-dz-thumbnail width=\"100%\"/></div><div class=\"dz-filename\">(<span data-dz-size></span>)</div></div>\n  <div class=\"col-sm-7 col-md-8\"><div class=\"row\"><div class=\"col-sm-12\"><input type=\"text\" id=\"itemtitle\" placeholder=\"Project title\"name=\"itemtitle\" class=\"info-title form-control\"></div>\n <div class=\"top-15 col-sm-12 \"><textarea id=\"itemdescription\" placeholder=\"Describe here the project with essential informations like material and methods applied.

    });

I don't know for certain, but at a guess i'd say it's because the ID you pass isn't on the page yet - it's in the preview template. So Dropzone tries to select an element that doesn't exist. Try putting the add-new button on the page before Dropzone is initialised.
