Javascript issue on dynamic table updation

The link below contains 2 files, one html and other javascript file. Open the html file, you will find a button, on clicking a button a row appears a textbox with a date in it and an image also appears. The issue is, on clicking the image, a calendar containing the date present in the text box should appear and on selecting any date from the calendar, the selected date should be updated in the text box, but it is not happening so. Kindly anyone please resolve this issue. (It would be great if the issue is resolved within javascript file rather than the html file).
