dynamically added modal buttons throwing errors in IE7

[o0Silas0o]

Hey,

I am adding modals dynamically with jQuery's prepend function. On all other browsers this is fine, the modals work perfectly. But on IE7 an error is thrown.
"Syntax error, unrecognized expression: http://10.0.1.4/#IC-99-modal-wrapper"

This is the markup for the button that is prepended to it's parent

This is the wrapper markup for the modal that is prepended to it's parent

This is the js I call when the page loads, inside jQuery document ready
$("a[rel*=modal]").leanModal({
top: 200,
overlay: 0.4,
closeButton: ".modal_close"
});

Has anyone else tried using leanModal with dynamically added elements?
