            $('#btn').attr("disabled", "disabled");
            setTimeout('enableButton()', 50);

You can't pass a string to setTimeout() here, since the function isn't global, instead pass a direct reference to the function, so change this:

setTimeout('enableButton()', 50);

to this:

setTimeout(enableButton, 50);

In general always try to do this, it'll avoid many issues...like the one you're having.

this:

<% Html.EnableClientValidation(); %> 

function enableButton() {
   $('#btn').removeAttr('disabled');
}

$(document).ready(function () { 

   $('#form1').submit(function () { 
       $('#btn').attr("disabled", "disabled"); 
       setTimeout(enableButton, 50);
   });

});

or this:

<% Html.EnableClientValidation(); %> 

$(document).ready(function () { 

   $('#form1').submit(function () { 

       var btn = $('#btn').attr("disabled", "disabled"); // ref to #btn

       setTimeout(function() 
         {
            $(btn).removeAttr('disabled');
         }
      , 50);
   });

});
