A search input don't open the search keyboard [solved]

Hi, I just start with jQuery mobile and I'm trying to do a search form.
It's very simple but I have an small issue, iphone keyboard show the button "Ir" (Go) instead of "Buscar" (Search).
I'm freaking out looking for a solution, but I don't find it.

This my source

<form method="get" action="#">
      <input type="search" name="address" value = "">
      <input type="button" id="buscar_farmacia" data-theme="a" value="Buscar dirección" />
</form>

Theres is an attachment with a screenshot.

I'm working with jquerymobile 1.0a2 and testing with iPhone 4 iOS 4.2

Thank you in advance, regards
