title: Angular js: how to use ngMousedown ngMouseup
body: <p>Is it possible to use ngMousedown for adding class to a div and ngMouseup for removing the class again?
  At the moment I use <strong>ng-mousedown="activateClass()"</strong> , in activateClass() change <strong>$scope.className="data-active"</strong> and change it again with other function with ng-mouseup. And use ng-class to add the class "data-active"
  I don't wanna use $scope.className and change it with function in controller, because this function is used for several divs and I don't want to add the class to all of the divs I have.</p>
  
  <p>Thank you.</p>
