Put simply I have an ajax call that sometimes completes before the page is loaded, so I tried wrapping the callback in $( fn ), but the callback doesn't fire if the page is loaded... Anyone have a good solution to this?

$.get( '/foo.json', function( data ){
    $( function(){
        // won't get here if page ready beats the ajax call

        // process data
        $( '.someDiv' ).append( someData );
    } );
} );

And yes, I know that if I flipped the order of those it would always work, but then my ajax calls would be needlessly deferred until the document is ready.
