How to finish adding your own parameter to the Bitrix component?

Question

PHP

All this is necessary in order to link news with the event calendar, I poke the date of the month and the news feed at the bottom.
The problem is that the default cannot be set. it is set by the infoblock itself.

now

Event date(DATA_SOBYTIYA) this property I display the property
in the component

//вывожу дату
  $IBLOCK_ID = intval($arParams['IBLOCK_ID']);
  //print $IBLOCK_ID;
  if(!CModule::IncludeModule("iblock"))
    die('iblock module is not included!');
  $arSort = Array("SORT"=>"ASC", "NAME"=>"ASC");
  $arSelect = Array("ID","NAME","PROPERTY_DATA_SOBYTIYA");
  $arFilterDate = Array(
    "IBLOCK_ID" => $IBLOCK_ID,
    "ACTIVE" => "Y", 
    ">=DATE_ACTIVE_FROM" => $curdate, 
    "!PROPERTY" => array('DATA_SOBYTIYA' => array('VALUE' => false)), 
    "<=DATE_ACTIVE_FROM" => $curdatelast
  );
  $obIBlockResult = CIBlockElement::GetList($arSort, $arFilter, false, false, $arSelect);
  $arFilter = $obIBlockResult->GetNext();
  $sDateEventsCustom = "12.09.2016";//$arFilterDate["PROPERTY_DATA_SOBYTIYA_VALUE"]

$sDateEventsCustom - here I somehow have to pass the DATA_SOBYTIYA property and display events based on it .
The filter that works on the page itself is $arFilterDate["PROPERTY_DATA_SOBYTIYA_VALUE"]

$arDay["events"][] = array(
            "time"=>$eTime,
            "url"=>$dayNews["DETAIL_PAGE_URL"],
            "title"=>$title,
            "preview"=>$sTitle,
            "DATA_SOBYTIYA"=>$sDateEventsCustom,//свойство должно что-то передавать 
            //"property"=>$sProperty,//свойство должно что-то передавать
            $arParams["DATE_FIELD"]=>$dayNews[$arParams["DATE_FIELD"]],
          );

Event in wardump

array(1) {
  [0]=>
  array(5) {
    ["time"]=>
    string(11) "19:17 "
    ["url"]=>
    string(56) "/dsaf/asfdfa/"
    ["title"]=>
    string(92) "авывыфавы"
    ["DATA_SOBYTIYA"]=>
    string(190) "выаыфва.."
    ["DATE_ACTIVE_FROM"]=>
    string(19) "18.06.2016 19:17:00"
  }
}

.parameters.php

$arDATE_FIELD = Array(
  "DATE_ACTIVE_FROM" => "[DATE_ACTIVE_FROM] ".GetMessage("T_IBLOCK_DESC_CAL_DATE_ACTIVE_FROM"),
  "DATE_ACTIVE_TO" => "[DATE_ACTIVE_TO] ".GetMessage("T_IBLOCK_DESC_CAL_DATE_ACTIVE_TO"),

  "DATA_SOBYTIYA" => "[DATA_SOBYTIYA] ".GetMessage("T_IBLOCK_DESC_DATA_SOBYTIYA"),
  );

template.php of the calendar itself

<?
//здесь я пропарсил url на основе его выводится текущая дата 
?>

      <tr>
