Bootstrap modal stops working after I sort portfol

I am building a sortable portfolio using quicksand.js, to display more information on click I am using bootbox.js, now this is working pretty well but I recently ran into an issue. When you sort the portfolio bootbox not longer works!

You can see this in action here, scroll to the portfolio section and click one of the images to see it function correctly. Then sort it and try again and you will see my issue.

Update: Using console I found what is causing the issue but I cant fully understand the error, I had to use jquery migrate at one point to make quicksand function and that is part of the issue. Here is the error:

console.trace()                        jquery-migrate-1.2.1.js:43

Here is my javascript:

<!-- End Portfolio -->

I havent had any luck with this if anyone could take look.

UPDATED: I saw that the quicksand plugin allows for a callback function.

I believe what's happening here is the elements are losing their event handlers when they get sorted due to the elements being cloned and the gallery() function only being called on (document).ready. The elements that display after being sorted are 'new' and have not got an event listener attached.

In portfolio.js, try calling the gallery() function after sorting the items via the quicksand callback argument

...

// call quicksand and assign transition parameters
$holder.quicksand($filteredData, {
  duration: 800,
  easing: 'easeInOutQuad'
}, gallery);

...

Also, I see that you have gallery as the callback in the code you posted here, but I don't think that's the code that is running. I think portfolio.js is what's running to do the sorting.
