set the color of specified row headers from code (not style!!)

How can i set the row header colors programaticaly?
I tried this:

function myColor(p){
var value = this.getProperty('item/index');
try{return getRowColor(value);}catch(error){}
return this.getProperty('background');
}
function myHeight(){
var value = this.getProperty('item/index');
try{return getRowHeight(value);}catch(error){}
return this.getProperty('height');
}
this.getTemplate('row', 0).setStyle('background-color', myColor);
this.getTemplate('left/item', 0).setStyle('background-color', myColor);
this.getTemplate('row', 0).setStyle('height', myHeight);
this.getTemplate('left/item', 0).setStyle('height', myHeight);

Only the heigth works. Why?
Tell me why????????????????????

Thank you amigo. but i am sure it doesnt work.
I used background-color, backgroundColor,background, whatever.
I tried these with the simpliest example from this site.

Hi,
I know this is a little late.. but I stepped over that same problem.
I found out, that it's not possible, because the different row headers have the same stylesheet-class.

So it's not possible to set diferent colors to different row headers.

(please tell me if that right or nonsense alex)

Greetings,

sintax goes like this :

this.getTemplate('row', 0).Style.backgroundcolor = myColor;
