When setFeatures is used the title area displays the number of features and the index of the currently selected feature and ignores the title defined in the info template. If you want to display title text you will need to specify it as part of the info window content.
Glad you got it working. The API documentation for FeatureLayer needs some work to say the least. I just got there by trial and error my self. You'l see in the sample they add the layer twice as well.
