ResetIsDirty on FCKeditor immediately after SetHTML -- Concurrency/timing issue with Javascript

Question

I am using IsDirty to check for changes in my FCKeditor. Unfortunately, it seems that its functions are asynchronous.

Here is the failing code:

var txtObj = $('activities').EstActText1.id;
var oEditor = FCKeditorAPI.GetInstance(txtObj);
oEditor.SetHTML(jsonObj.DATA.ESTACTTEXT1.toString());
oEditor.ResetIsDirty();

The problem is, SetHTML does not take effect immediately (if you put a check right afterward using GetHTML, it will return what was previously in the textarea). Thus, ResetIsDirty will run, THEN the HTML will actually be changed, and the dirty flag will be set again.

Is there any way I can force the SetHTML call to complete before continuing? If not, is there any way (besides a ghetto setTimeout call that will add latency and not necessarily always work) to make sure that the ResetIsDirty will actually take effect after the HTML is changed?
