var end = moment();

Answer 1

if this line cb(start,end); overwrite your text box on post back, then do that.

Add on aspx page one literal to render the variable isPostBack as javascript.

Then on code behind render it.

txtExtraScriptVariables.Text 
    = string.Format("var isPostBack = {0};", IsPostBack.ToString().ToLower());

and now on your script use it as

if(!isPostBack)
    cb(start,end);
