Image preview issue with cgi-callout on datacapture form

System

I have image preview feature enabled on the datacapture template. The image shows up when I browse for an image and say ok. The code snippet as follows.

IWDatacapture.enableImagePreview(true);

The issue is with the file upload component (cgi-callout) which is called on click of the callout button placed right next to the browse button. The preivew image does not show up when I upload the image. The image upload component puts the image path back in the browse text box, but it doesn't do whats necessary to show that image on the datacapture form.

I have this snippet my cgi-callout javascript. But, it doesnt help.
...
..
calloutForm.elements.value = path;
opener.top.datacapture.refreshForm();
calloutElementFound = true;
...
..

Please let me know if I you have any idea. I am on TS65/solaris.
