Jsp popup page is not reloading when its called second time

Question

Hi i have one pop called ManageData, form this popup i need to redirect into another page while clicking on add button.

<input type="button"
        onclick="javascript:popup('loadaddPrtyCrnToStmt.action?statementId=<s:property value="statementId"/>','add')"
        value=<s:text name="button.addMore"/>

From that page, if all operations are completed i will return to this page.Again if i click on add button, action is not triggered. What ever showed on first time same data is showing again.
