Question

I hava a functoin that call himself occasionally, that function has some asynchronous call to update the content of the page, but it always fails when it calls itself.

Answer 1

trunpet, I suggest you use setInterval instead of recursive calls.

setInterval(yourFunctionName,miliseconds);

you can even pass an annonymus function

setInterval(function(){
    //do your stuff here
},miliseconds);

whre miliseconds is the time interval betwen each call.
Something you might want to do is store the interval in a variable so you can kill it later.

var interval = setInterval(yourFunction,miliseconds);
clearInterval(interval);

warning: avoid calling it more than once without killing it first.
