Trying to translate the texts in a combobox

I am trying to translate the texts attached to the thumbnail in the combobox, which are taken from the title and info that are in the scene header
    
I can't get the title and info texts to be translated but it does show them correctly in the first language, which is Spanish.
All other texts other than the combobox are translated correctly.
What is missing in this code?

<scene name="scene_40ena" title="link:translate('ab1_content')" onstart="" thumburl="panos/40ena.tiles/thumb.jpg" lat="" lng="" alt="" heading="" info="link:translate('t1i_content')" >

<!-- different languages texts -->
<languages name="es" displayname="ES"
title_enc="Centro de entrenamiento" subtitle="Espacio para los procesos de selección y capacitación continua"
latsup="Maravillosa actualización" latinf="Difícil de entender [br]para quienes no somos codificadores[br] es un poco arduo[br] pero aprenderemos"
titulo="Dojo: Simulación de procesos "
infoena="Cuarentena[br]de esquejes"
ab1_content="Cuarentena"
t1i_content="Cuarentena[br]de esquejes"/>

<languages name="en" displayname="EN"
title_enc="Training center" subtitle="Space for selection processes and continuous training"
latsup="Wonderful update" latinf="Difficult to understand [br]for those of us who are not coders[br] it's a little arduous[br] but we will learn"
titulo="Dojo: Process simulation "
ab1_content="Quarantine"
t1i_content="Quarantine[br]of cuttings"/>

I have also tried this but I can't get it to work:

scene name="scene_40ena" title="Cuarentena" template="[div style='combobox_item_style;']{{translate('ab1_content')}}[/div]" onstart="" thumburl="panos/40ena.tiles/thumb.jpg" lat="" lng="" alt="" heading="" info="Cuarentena[br]de esquejes" >
