			rnia:'='
		},
		link: function (scope,element,attrs){
			var optionsObj={
				dataType:'json'
			};
			//if have done attribute in the directive
			if(scope.done){
				// done in optionsObj is a success callback function
				optionsObj.done=function(e,data){
					scope.$apply(function(){
						//event and object
						scope.done({e:e,data:data});
					});
				};
			}
			// fileupload: widget initialization!
			// Usually, file uploads are invoked by selecting or dropping
				element.fileupload(optionsObj);

			//imp! no (scope,element,attrs)
			scope.submitRNIA = function(){
				//todo:
				optionsObj.formData=attrs.rnia;
