Android Checkboxs with ListView

This is a tough situation to explain. I have a main activity that has actionbar tabs to cycle through different fragments. The first tabbed fragment that gets loaded has a listview that can scroll with checkboxes. What happens is when you first run the app, if you click on a checkbox, it doesnt check. However if you click on another tab and then click back everything works correctly.

I've looked at a lot of other situations where people havent had checkboxes work with scroll views and i've implemented their solution so i would consider my situation fixed as well due to the fact it works when you after you tab over.

Any thoughts as to why it would work the first time the view gets loaded? I know its a difficult question to ask and i dont think posting code would really help. Thanks guys.
