Change to Visualization Y-Axis aggregation not reflected in data table

[LeeDr]

I see this on 4.5.1-rc1 (although I doubt is has anything to do with the node version bump in this rc.

I'm using Chrome browser. Same problem on Firefox.

Notice that the data table second column is "Sum of phpmemory" but I had previously changed the Y-Axis aggregation from phpmemory to bytes and applied that change. The green Go arrow is currently disabled so it's not a change that hasn't been applied.

If I collapse the data table (expand the chart) and then show the data table again it is properly updated to the new Y-Axis agg (and notice that the numbers didn't change, so I think it was showing correct numbers with a stale heading);

In this gif I change from phpmemory to bytes, and you see that the data table still shows phpmemory until I collapse and expand it;

I verified that the same problem exists in Kibana 4.4.2.

this is present on master as well and it doesnt just affect data table. whole spy panel doesn't refresh until you collapse/expand it again.

@thomasneirynck @ppisljar
The spy table headers do not update because the paginated-table directive uses a one-way data binding ::columns. Is there a reason why the table headers are rendered with a one-way data binding?

[ppisljar]

@nreese no idea, maybe @spalger knows ?

@nreese @ppisljar there was a minor obsession with bind-once behavior a while back, but the only reason it's useful is performance (It's not actually one-way data binding) it can be safely removed since it's not actually benefitting us here
