d3js update with div and attributes - d3.js

Question

I am struggling with an update on d3js. The code below if uncommented does not update the values - actually, the initial layout disappears.
I cannot figure out yet. I just want the price to be updated.
Any help would be greatly appreciated.
updated
Someone (anonymous) updated http://jsfiddle.net/1qqdc0ns/11/ - so I am looking into this one.
I have cleaned my original version into http://jsfiddle.net/1qqdc0ns/12/ which still does not update properly.
function update(data) {
console.log("update " + data);
var quotes = d3.select("#quoteContainer")
.selectAll("div")
.data(data);
// ENTER
var q = quotes.enter()
.append("div")
.attr("class", "quotePanel");
var m = q.append("div").attr("class", "carmodel");
var p = q.append("div").attr("class", "price");
var f1 = p.append("span").attr("class", "bigFigure");
var f2 = p.append("span").attr("class", "smallFigure");
f1.text(function (d) {
var priceStr = d["price"].toString();
var bigFigure = priceStr.substr(0, 4);
console.log("bigFigure: " + bigFigure);
return bigFigure;
});
f2.text(function (d) {
return "00";
});
quotes.select("div").text(function (d) {
var modelname = d["symbol"];
console.log("Setting model name " + modelname);
return modelname;
});
//quotes.exit().remove();
}
function onclick() {
update([{
"symbol": "BMW",
"price": 9000
}, {
"symbol": "PIGEOT",
"price": 124
}]);
};
d3.select('#update')
.on("click", onclick);
update([{
"symbol": "ASTON",
"price": 3000
}, {
"symbol": "MARTIN",
"price": 6500
}]);

Thanks Igor.
The solution is:
http://jsfiddle.net/Ihorad/1qqdc0ns/14/
function update(data) {
var quotes = d3.select("#quoteContainer")
.selectAll(".quotePanel")
.data(data);
var q = quotes.enter()
.append("div")
.attr("class", "quotePanel");
var m = q.append("div").attr("class", "carmodel");
var p = q.append("div").attr("class", "price");
var f1 = p.append("span").attr("class", "bigFigure");
var f2 = p.append("span").attr("class", "smallFigure");
quotes.select(".carmodel").text(function (d) {
var modelname = d["symbol"];
return modelname;
});
quotes.select(".bigFigure").text(function (d) {
var priceStr = d["price"].toString();
var bigFigure = priceStr.substr(0, 4);
return bigFigure;
});
quotes.select(".smallFigure").text(function (d) {
return "00";
});
quotes.exit().remove();
}
