updating highcharts data with datepicker directive

[Brad McAlister]

Howdy,

I'm using Highcharts and this date picker directive and what I'm trying to do is be able to edit the start & end date of each data item in the chart. I've gotten fairly close but I'm having trouble figuring out why the new values won't push back into the model. The way I'm doing it now seems pretty bad but I wasn't able to figure out a way to make the whole process more dynamic and driven by how many data items there are in the model. Any help to make this thing better and actually work correctly is much appreciated.

Thanks,

Brad
