Tooltip doesn't work in chart

I’m trying to use jquery flot chart from this example:

Chart is working but the tooltip doesn’t show up. When I remove ionic.bundle.js then it works great. I use Ionic 1.3.1.
I think the problem might be somehow connected to fadeIn function, but I am not sure… It’s because of some code in ionic.bundle.js - as I said without ionic.bundle.js it works.

$("#tooltip").html(item.series.label + " of " + x + " = " + y) .css({top: item.pageY+5, left: item.pageX+5}) .fadeIn(200);

I have just copy pasted the code from official example into a blank starter app. Here is my code:

Any ideas?
