You can wrap the string in jQuery and get the id of element.

$(btn_response).attr('id');

data() is used to get data-* attribute value. Use attr to get the id attribute value.

$(uploadBtn).data("id") will search for data-id attribute, which is not available so returns undefined.

Use:

$(uploadBtn).attr("id")

Demo:

var btn_response = '<input type="button" id="upload-btn5" style="margin-bottom: 7px;" class="btn btn-success clearfix" value="Choose file">';

alert($(btn_response).attr('id'));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
