I cant find the way to get child item ID in my foreach loop, which i use for accordion. I want to do this because each accordion must have diferent ID because of collapse. If i use this @Umbraco.Field("pageID") , i got ID from parent page. And i want id from each list item in parent page. This is my code:

<section class="container">
    <h3>Opis pojedinačnih sustava veza</h3>
    <div class="panel-group" id="accordion">

        @{
            var selection = Model.Content.Site().FirstChild("mototrboSistems").Children("mototrboItems").Where(x => x.IsVisible());
        }
        @foreach (var item in selection)
        {

            <div class="panel panel-default">
                <div class="panel-heading" data-toggle="collapse" data-parent="#@Umbraco.Field("pageID")" href="#1">
                    <h4 class="panel-title">
                        @item.Name
                    </h4>
                </div>
                <div id="@Umbraco.Field("pageID")" class="panel-collapse collapse">
                    <div class="panel-body">
                        <div class="row">
                            <div class="col-sm-10">
                                <h4>@item.GetPropertyValue("subtitle")</h4>
                                <p>
                                    @item.GetPropertyValue("textBody")
                                </p>
                            </div>
                            <div class="col-sm-2">
                                <img class="img-responsive" src="~/Images/direktanNacin.png" />
                            </div>
                        </div>
                        <div class="row">
                            <div class="col-sm-10">
                                <h4>Podržavaju sljedeće radio stanice:</h4>
                                <p>
                                    @item.GetPropertyValue("podrzaneRadioStanice")
                                </p>
