On my web site i listen for clicks on a href and swap my html using ajax using the code below

$(document).on('click','a', function (e){
e.preventDefault();
$.ajax({})
.........
})

but the prevent default prevents me from clicking any other thing on the page until the ajax complete. I am listening to the click on tags while referencing the document as root because if the ajax swaps the content, using just and listening to events on that won't be called because of the changes done by swapping the dom. What can be done to fix this behavior. Thanks
