JQuery :: Prevent Default Submit In Dom And Replace With Submit And Onclick?

I have a DOM loaded from a remote site, i cannot alter that page. The DOM has a input:submit in the form that looks something like this:

<FORM NAME="frm1" METHOD="POST" ACTION="ServletController;jsessionid=72CDF83C126FFF9D87821CE9E9B9E860.fre01" onSubmit="return checkFormSubmit();">
<input type="hidden" name="mode" value="apply">
<input type="submit" name="Apply" value="Apply" onClick="return applyClicked();">
</FORM>

I need to replace the default ACTION with an ajax post with the current form data, but I also need to keep the:onClick="return applyClicked(); here is what works, however I cannot get the return applyClicked() to prevent the submit if it is false.

[Code]...
