Polymer function not accessible in firefox/safari

[prateekbh]

So I made a polymer element.
and in the script part i wrote this

<script> Polymer({ renderEvents:function(e,shipment_id){ this.events=e.events; this.shipment_id=shipment_id; } }); </script>

And in my JS controller i wrote:

var timelineEl=document.querySelector(".timeline-shipment");
console.log(timelineEl);
timelineEl.renderEvents(data,$scope.shipment_id);

This works fine in chrome but not in firefox/safari...
I had to do this:
timelineEl.proto.renderEvents(data,$scope.shipment_id);

So i was using a SPA
and the other view which loaded via ajax was bringing in new polymer tags
so it was not getting initialised before i accessed them..
any way of knowing such initialisation event?
