Try and set the text in the feature's properties:
feature.properties.text = mytext;

and then add a style to the layer you place the feature in:

  var style = new OpenLayers.Style({
  label: "${text}",
});

(a bit confused about your code snippet, is the event in featureAdded 
indeed the created feature?)
