Mutiple standonle buttons with Laravel Unisharp file manager

I am using Laravel 5.4 Along with UniSharp/laravel-filemanager and its working fine. All i need to know who can i use multiple standalone buttons on same form ?

Note: i can upload single file,but using multiple whenever i update any filed it only updates the first one.

Here is the my Js code.

 $(function () {

        var domain = "";
        $('#image1').filemanager('image', {prefix: domain});
        $('#image2').filemanager('image', {prefix: domain});
        $('#image3').filemanager('image', {prefix: domain});
    })
