I'm having an issue submitting a form with the jquery .submit();

I don't have any elements on my page with a name of name="submit" or name="Submit", same goes for id's.

My bit of jQuery code is as follows:

    $(document).ready(function () {

    $(document).on('click', "#appSubmit",function(e){

            e.preventDefault();
            var value = $("#time").val();
            if(value == "--"){
                $( "#err-time" ).dialog( "open" );
            }else{
                alert("1");
                var dummy = $("#appSubmit").val();
                alert(dummy);
                $("#appSubmit").submit();
                alert("2");
            }

    });
});

All of the alerts work properly, even the alert(dummy); prints out the correct value. The alert("2"); prints out, so it isn't even breaking on the $("#appSubmit").submit();

My submit button is

<input type="submit" name="appSubmit" id="appSubmit" value="Apply">

Any thoughts would be appreciated, thanks.
