Update Hidden Custom Attribute In Element

[benlbit]

I am trying to update an attribute attached to the element triggering the DateRangePicker.

e.g.

I am trying to update the attribute(s) within the callback function

function (start, end) {
this.element.hstartvalue = start.format();
this.element.hendvalue = end.format();
}

Problem is the DOM isn't being updated by the callback.

Is there a proper way to access the element of which the DateRangePicker is attached?

I need the callback function to specifically update the node because I have a large number of DateRangePickers attached to a large number of text inputs contained in a list.
