Strange Popup Behavior with Multiple GP Tool Links

I'm working on a script with GP tools in a popup window. On click, the popup displays the lat/lon coordinates and two GP tool links. One of these is an ESRI sample tool that calculates population, the other generates a chart with a matplotlib script tool.

I'm getting some weird behavior with the inner HTML when I run the population tool. It says "calculating" Where it said "Three Week Chart," when  "Calculate Population" should be replaced with "calculating" instead.

If I click on another point, I get this:

I'm not sure how to fix this. Here is the relevant portion of my script.
