Problems with internationalization in ActionBar

Hello,

I want to set language depends on the settings, for intance if user has set English I show my app labels, buttons, etc in English. I already do with the buttons and labels, however when I try to apply in the actionBar I get this: ALLOY_EXPR--L('actionPet'), I am doing it in android so I have my files platform/android/res/values-en and values-es.

My tss is:

'#actionPet': {
    icon: '/actionicon.png',
    displayHomeAsUp: true,
    title: L('actionPet')
    //backgroundImage: "/actionbackground.png"
   }

<Alloy>  
 
 
    <Window id="pet" class="container" layout="vertical" theme="Light" >    
 
                <!--MENU -->
                    <ActionBar id="actionPet" /> <!-- onHomeIconItemSelected="onClick"-->
 
                    <Menu>
                        <MenuItem title="Nuevo" onClick="galeria" />
                        <MenuItem title="verMascota" onClick="verMascota"></MenuItem>
                    </Menu>
                <!--END MENU -->
             <View>
                <TableView id="table" onClick="openDetail"></TableView>
            </View>
    </Window>
</Alloy>

<?xml version="1.0" encoding="UTF-8" ?>
 
<resources>
    <string name="lblUsuario">username</string>
    <string name="lblPassword">password</string>
    <string name="btnSignIn">Sign in</string>
 
 
    <!-- ActionBars -->
    <string name="actionPet">My Pet</string>
</resources>

Do you have any thoughts to solve this issue?

I already set directly the title from the .tss file and works, I already check many times the names and all match.

Thank you in advance for any help.
