Datatables with ajax response (Use of undefined constant)

How to use a JavaScript variable inside Blade syntax? I'm getting an error:

Use of undefined constant buttonID

inded.blade.php

var t = $("#datatable").DataTable({
    "order": [[ 1, 'asc' ]],
    "ajax": "questions1/get-data",
    "deferRender": true,
    "processing": true,
    sAjaxDataProp: "",
    "columns": [
        { "data": "id" },
        { "data": "name" },
        { "data": "description" },
        { "data": "answers.[, ].name" },
        { "data": "campaigns.[, ].name" },
        { "data": "label" },
        {
            sortable: false,
            "render": function ( data, type, full, meta ) {
                var buttonID = full.id;
                return '@can('delete', $question){!! Form::open(['method'=>'DELETE','url' => ['/admin/survey-details/questions', buttonID ],'style' => 'display:inline']) !!}{!! Form::button('<span class="glyphicon glyphicon-trash" aria-hidden="true" title="Delete Question" />', array('type' => 'submit','class' => 'btn btn-danger btn-xs','title' => 'Delete Question','onclick'=>'return confirm("Confirm delete?")')) !!}{!! Form::close() !!}@endcan';
            }
        }

    ],

});
