[jQuery] Checkboxes, difference in browsers

[[EMAIL PROTECTED]]

Hello.

I have this JQuery code which works absolutely fine in Firefox:

if ($("#createNewAccount").is(":checked")){
     // do stuff
}

The variable 'createNewAccount' is defined as follows:

<input type="checkbox" name="createNewAccount" id="createNewAccount">

But this simply will not work in IE. What am I doing wrong please?
