Hey this solution works. for download we should be using MSBLOB

$scope.getSingleInvoicePDF = function(invoiceNumberEntity) {
   var fileName = invoiceNumberEntity + ".pdf";
   var pdfDownload = document.createElement("a");
   document.body.appendChild(pdfDownload);

   AngularWebService.getFileWithSuffix("ezbillpdfget",invoiceNumberEntity,"pdf" ).then(function(returnedJSON) {
       var fileBlob = new Blob([returnedJSON.data], {type: 'application/pdf'});
       if (navigator.appVersion.toString().indexOf('.NET') > 0) { // for IE browser
           window.navigator.msSaveBlob(fileBlob, fileName);
       } else { // for other browsers
           var fileURL = window.URL.createObjectURL(fileBlob);
           pdfDownload.href = fileURL;
           pdfDownload.download = fileName;
           pdfDownload.click();      
       }
   });
};

For AngularJS or even for normal javascript.
