Selectize plugin which gives an option to clear selection

clear_selection.js

Selectize.define( 'clear_selection', function ( options ) {
    var self = this;

    //Overriding because, ideally you wouldn't use header & clear_selection simultaneously
    self.plugins.settings.dropdown_header = {
        title: 'Clear Selection'
    };
    this.require( 'dropdown_header' );

    self.setup = (function () {
        var original = self.setup;

        return function () {
            original.apply( this, arguments );
            this.$dropdown.on( 'mousedown', '.selectize-dropdown-header', function ( e ) {
                self.setValue( '' );
                self.close();
                self.blur();

                return false;
            });
        }
    })();
});

Working Fiddle

Is there an easy way to override the title?

@LeonB Take a look at my fork!

Isn't there any way to initialize the plugin after I update the selectize placeholder, so I can pass new placeholder as plugin title?

This is what I've tried, but it's not working

    selector.settings.placeholder = selected_category.adv_main_property_title;
    selector.updatePlaceholder();
    selector.initializePlugins({ 'clear_selection': { title: selector.settings.placeholder } });

P.S. when I console log selector.plugins.settings.clear_selection I can see my placeholder as a title there
