Image caption/Description in DOCX images

Hi , 

We are facing issues in  placing image description/caption below images in dynamic DOCX from Template.

Passing below XML data model and image shows the corresponding DOCX template.  Please suggest any other way we could display description below images in DOCX.

<value>
<count>6</count>
<imageDescription>desc1</imageDescription>
<imageDescription>desc2</imageDescription>
<imageDescription>desc3</imageDescription>
<imageDescription>desc4</imageDescription>
<imageDescription>desc5</imageDescription>
<imageDescription>desc6</imageDescription>
</value>
