Pass Values to Edit Form thru Query String and Save in List

I have developed a custom Edit form from SharePoint Designer and I am passing values thru Query String as below;

http://<>/cli/acc/Lists/GIInfo/testEdit.aspx?ID=262&com=POD_Send

And, user supposed to save the form directly without changing the values came thru Query String as below. 

Now, issue is, when user saves the form, values is not getting saved. It saves when we change the value in text box or when we do a text change event in form. Becasue data binding says Text Change even in data binding property.

__designer:bind="{ddwrt:DataBind('u',concat('ff22',$Pos),'Text','TextChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Actions')}"/>

Kindly guide me what is the issue, or correct approach to do that? I want to pass values to Edit Form thru Query string and save in List without changing those.
