[jQuery] What am I missing with jQuery Forms ajaxSubmit?

[jQuery] What am I missing with jQuery Forms ajaxSubmit?


Hi
This is my script:
    $("#frmTargets").submit(function(){
     var frmTargetsOptions = { 'dataType':'json', target:
'#output', 'success':addTargetsResponse, 'error':
addTargetsResponseFailed };
$(this).ajaxSubmit(frmTargetsOptions);
return false;
});
I'm posting to a .NET ashx. All the post works fine and the .Net code
does it's stuff correctly.
But instead of getting the JSON response from this code:
context.Response.ContentType = "application/json"
context.Response.Write("{""status"": """ & status & """}")
context.Response.End()
my browser (Firefox 2.0.0.1.1) gets the ashx and tries to open it in
an eternal app.
What I am doing wrong?
Many thanks.
