I tried to set background for genlist; elm_bg_color_set(bg, 255, 0, 0); but it seems not work.

Even I do it step by step as below turorial link, no color is showed for the item of genlist.

You can see a function definition for _genlist_content_get() in this tutorial, but it seems not work at all!

Who ever set the background for genlist item successfully?
