[jQuery] jFrame API Call

I am trying to combine a jFrame target div load with a couple of other
functions. I can get the jFrame call w to work as such:
$(myTargetElement).loadJFrame(myNewURL, myCallback);
Problem is, calling this function directly does not render the
"loading content..." preload that is defined, not does it actually
update the target element.
Any ideas if this is possible?
