Title: Feature a d buttons

The choose button is still not clickable, but I know why that is. The choose module is being placed in front of the button for some reason, all I did was click "inspect element" on the button and you can see the module that appears over it.

You can use this if you just want to test the attach and detach feature:
$("[data-target='#photoListModal']").trigger("click");

After you run that code you should be able to click on the button just fine if you cancel out of it. It pops up the module again if you choose the attach feature though.
