如何清除bootstrap-confirmation.js弹出窗口中文本框的内容？

Question

I have gridview. In that gridview i have an Icon. if the icon is clicked then the bootstrap popover with textbox and two buttons will be opened. If i filled on that textbox of the popover and then i clicked outside of the popover, then the popover will be closed. and then again if i clicked that icon, the popover will be opened. but the textbox is not empty. the old value is place on that textbox.

Can anyone say, how to empty bootstrap popover textbox, when the popover is opened?

My code is:

<img src="Images/icon.png" data-title="Name" data-btnoklabel="Update"
        data-btncancellabel="Cancel" data-textbox="true" data-popout="true"
        runat="server" data-placement="left" data-toggle="confirmation-singleton"
        data-original-title=""
/>

Answer 1

1)-Lets suppose you have a function for closing the popup .`

2)-You have two textboxes in the popup with ids txt1 and txt2

When function will be fired :-

 function ClosePopup(){
     //clear all the values 
     $("#txt1,#txt2").val("");
  }
