Aurelia passing data into bindable value of template

I some template where i'm using repea.for some times. There is a problem when I'm trying to bind data into bindable variables inside <editable-file-upload> component.

I want to pass it like <editable-file-upload elem-id.bind="${elem.parent.id}">Upload</editable-file-upload> but getting an error - aurelia-logging-console.js:54 ERROR [app-router] Error: Parser Error: Missing expected : at column 7 in [${elem.parent.id}] . If I'm passing it so <editable-file-upload elem-id.bind="elem.parent.id">Upload</editable-file-upload> value is undefined. But it can't be undefined, because inside div.files-wrapper I'm typyng those values and see right ones. How to pass it? I can't understand.

<div class="row">
    <div class="col-md-12">
        <div class="panel-group" id="someid" role="tablist" aria-multiselectable="true">
            <div class="panel panel-default" repeat.for="elem of elems">
                <div class="panel-heading" role="tab" id="${elem.parent.id}-heading">
                    <h4 class="panel-title">
                        <a role="button" data-toggle="collapse" data-parent="#elems" href="#${elem.parent.id}" aria-expanded="false" aria-controls="#${elem.parent.id}">
                            <i class="glyphicon glyphicon-triangle-right"></i>${elem.parent.kood}
                        </a>

                    </h4>
                </div>
                <div id="${elem.parent.id}" class="panel-collapse collapse" role="tabpanel" aria-labelledby="${elem.parent.id}-heading">
                    <div class="panel-body">

                        <div class="elem" if.bind="!elem.children.length">
                            <div class="files-wrapper">
                                <div class="files-message">Toimingul ei ole veel malle.</div>

                                <editable-file-upload elem-id.bind="${elem.parent.id}">Upload</editable-file-upload>

                            </div>
                        </div>

                        <div class="sub_elems" if.bind="elem.children.length">

                            <div class="sub_elem" repeat.for="subElems of elem.children">

                                <div class="sub_elem-title">${subElem.kood}</div>

                                <div class="files-wrapper">
                                    ${elem.parent.id}
                                    ${subElem.id}
                                    <div class="files-message">Some text</div>

                                    <editable-file-upload elem-id.bind="${elem.parent.id}" sub-elem-id.bind="${subElem.id}">Lae üles</editable-file-upload>


                                </div>

                            </div>

                        </div>
                    </div>
                </div>
            </div>

        </div>
    </div>
</div>

You're inside a repeat.for and the property you want access belongs to the parent scope. So, you have to use $parent keyword to get to the parent scope and then access the property. For instance:

<div class="files-wrapper">
  ${$parent.elem.parent.id}
  ${subElem.id}
  <div class="files-message">Some text</div>

    <editable-file-upload elem-id.bind="$parent.elem.parent.id"
                          sub-elem-id.bind="subElem.id">
     Lae üles
   </editable-file-upload>
  </div>
</div>
