Manually set "Return" key alternative on Galaxy Ace

Question

there is a simple app (html + js + phonegap) and a login form with these two inputs:

<form id="loginForm">
    <input type="email" id="email" value="" class="email" placeholder="Email" >
    <input type="password" id="password" value="" class="password" placeholder="Password" >
</form>

On a samsung galaxy ace (android 2.3.6) I want to transform the return key to a "Next" key on the email input, and in the password field I want the return key to be a "Go" (now I have a "Go" on the email and a return on the password).

How can I achieve this (using html/JS)?

Important: I'm using iScrol, note that if I remove iScroll I get a "Go" key in both inputs, so in a strange way this point may be relevant.

Thank you all.

Answer 1

As stated here: question

"there is no way from JavaScript or HTML to affect the behavior of the Android soft keyboard."

I'll take this as the correct answer for now, but other answers are still welcome.
