Query for ajax added items

Hello everyone, I have elements in one page:

consul date

Each page is about a video game, so the number of consoles is variable, I in the blade have:

  @foreach($giochi->infogiochi as $info)
  <div id="stxrelease" class="form-group card col-12">
    <div class="card-body">
      <h3>Data di rilascio</h3>
      <div class="row">
        <div class="col-12">
            {{ Form::label('console', 'Console') }} <br />
          <select class="col-12 form-control select2" name="release" style="width:80%">
            @foreach($console as $value)
              @if($info->id_console == $value->id)
              <option value="{{ $value->id }}" selected>{{ $value->nome_cat }}</option>
              @else
              <option value="{{ $value->id }}">{{ $value->nome_cat }}</option>
              @endif
            @endforeach
          </select>
        </div>
        <div class="col-12">
            {{ Form::label('genere', 'Data di pubblicazione') }} <br />
          <input class="form-control datepicker" type="text" name="releasedata{{$info->id}}" value="{{$info->data}}">
        </div>
      </div>
      <div class="mt-2 col-12 text-right">
        <button data-target="#stxrelease_{{ $info->id }}" class="btn btn-danger remove_field" type="button" name="button">Elimina</button>
      </div>
    </div>
  </div>
  @endforeach

other items will be added via a <button data-node-template, of course I will not be able to enter $info->id not knowing the console that will be inserted and how many.

is it possible to make such a request?

foreach ($request->release as $value) {
    if($request->release) {
        $query = New RichiestaGioco();
        $query->id_utente =  \IPS\Member::loggedIn()->member_id;;
        $query->id_gioco = $giochi->id;
        $query->tipo = '1';
        $query->genere = '6';
        $query->dato  = '["id_console": '.$value->release.', "data": '.$value->releasedata.']';
        $query->status = '1';
        $query->save();
    }
}

basically I would like to save the changed data of all requests, only if changed...

My main problem is:

• can I make a general request and repeat it for each item on the page?
• how can I request an added element with data-node-template?

here an image to make you better understand how the page will be structured...
