CAn someone troubleshoot my converter?

Content

I have an oj-input-date-time that I want to format in the clients local timezone.  I have created this JS

  PageModule.prototype.convertToLocalTimeZone = function() {
    return [{
      converter: {
        "type": "datetime",
        "options": {
          "pattern": "MM/dd/yy hh:mm a", 
          "isoStrFormat": "utc",
          "timeZone": Intl.DateTimeFormat().resolvedOptions().timeZone
        }
      },
    }];
  };

and tried to set it as follows

            <oj-input-date-time value='[[typeof $current.data === "string" ? $current.data : null]]' readonly="true" :id="[['oj-input-date-time-548690015-1-' + $current.index]]" converter='{"type":"datetime","options":{{ $page.functions.convertToLocalTimeZone() }}'></oj-input-date-time>

 

I've also tried to return it as an object literal, and also as a single object instead of an array of cardinality 1 but no such luck.  Any help would be appreciated
