Thanks for you fast answer Christophe !
Here is the new code for my radioGroup :
<t:radiogroup t:id="suggestionRG" value="selectedSuggestion"
encoder="suggestionEncoder">
<t:loop source="suggestions" value="suggestionLoopValue"
encoder="suggestionEncoder">
<t:radio t:id="radio" value="suggestionLoopValue"/>
<t:label for="radio">${suggestionLoopValue.label}</t:label>
</t:loop>
</t:radiogroup>
It works!
Many thanks.
