The way to change icon based on the level:

jQuery('#tree-edit').on('changed.jstree', function(e, data) {

      //do something
    }).on("open_node.jstree", function(event, data) {
        jQuery.each(data.instance._model.data, function(key, val) {
            console.log(key + ", " + val);
           if (key.length < 4 || key=='#') {
               jQuery.jstree.reference("#tree-edit").set_type(val, "selectable");
           }
        });
    }).on("loaded_node.jstree", function(event, data) {
        console.log(data);

    }).jstree({
        'plugins': ["search", "types"],
        'core': {
            'data': {
                'url': 'http://www.google.com/json',
                'data': function(node) {
                    return {'id': node.id};
                }
            }
        },
        'types': {
            'selectable': {
                'icon': 'http://elpidio.tools4software.com/images/icon-ok-small.png'
            },
