Solution is pretty simple since you are using directive or component - just manipulate DOM on the right moment. Take a glance here:

app.component('myComponent', {
    templateUrl: 'tmpl.html',
    bindings: {
        str: '@'
    },
    controller: function ($element) {
        this.$postLink = function () {
            $element.find('input').attr('multiple', 'multiple');
        }
    }
}
