Dynamic binding in AngularJS with ng-repeat allows for seamless updating of data

I recently started using a helpful library called Angular Material File input

<div layout layout-wrap flex="100" ng-repeat="val in UploadDocuments">
    <div flex="100" flex-gt-sm="45">
        <div class="md-default-theme" style="margin-left:40px; color: #666666">{{val}}</div>
        <div style="margin-top:-8px;">
            <lf-ng-md-file-input lf-files='$parent.files' lf-api="stimg" ng-disabled="!enableFileBrowse"> </lf-ng-md-file-input>
        </div>
    </div>
</div>

My goal is to dynamically generate lf-files='$parent.files', such as lf-files='$parent.file1', lf-files='$parent.file2', lf-files='$parent.file3', based on the iteration in ng-loop.

Unfortunately, the commonly used trick of 

lf-files='$parent.file{{$index}}'
is not yielding the desired results.

Can anyone provide guidance on how to achieve dynamic generation?
