I create JSON object as:
var myJsonObject = JSON.stringify(objectString)
How I can add another item into myJsonObject??

myJsonObject is now a string you cannot add anything to it again until you change it back into a JSON object.
So you can technically do:
var myJsonObject = JSON.parse(myJsonObject); //change to obj
myJsonObject.somethingnew = true; //add something
myJsonObject = JSON.stringify(myJsonObject); //change back to string

Looks like you're re-serializing the string rather than parsing it.
var myJsonObject = JSON.parse(objectString);
then you can add a new item by using
myJsonObject['newItemName'] = newValue;
Hope that's clear.

If you mean you want to have an array of objects, you can do it like this:
//create an array with the result of your object (see the [] characters)
var myJsonArrayObject = JSON.stringify( [ objectString ] );
//add a new element to the array: parse the JSON, push the new element and stringify again:
JSON.stringify( JSON.parse( myJsonArrayObject ).push( newObject ) );
JSON.stringify()? don't you meanJSON.parse()?
