I have a script that create a button on the fly with JS... actually a table with diffierent button i want to change the text onclick whenever a user click on one of them....

Code JavaScript:
// Insertion d'une colonne contenant le Boutton de Suppression 
                			var celluleButton = document.createElement("td");
             				celluleButton.id = 'celluleButton';
   							celluleButton.innerHTML = '<input type="button" id="button_selected" name="sl_json_selected_' +SmartLink.id_source+ '" value="Supp" onclick="suppLienCible()">';

i have tried this but doesn't work

Code JavaScript:
function suppLienCible()
document.getElementById.value('button_selected') = 'Retablir';
return true;
