I faced similar issue with angular custom directive.

below was my custom directive:

function customDirective() {
      return {
        scope: {
          model: '='
        }
        link: function(scope) {
                scope.resetModel = function() {
                    scope.model.name = null;   //In these lines I was getting the above 
                    scope.model.email = null;  //mentioned warning in webstorm.
                }
            }
      }
}

After going through the $compile docs, I decided to use the below code which solves this warning and works fine with the binding to child and parent scopes, yes of course unless until your model is an object reference.

function customDirective() {
       return {
         scope: {
            model:'<' // Please refer the above linked angular docs for in detail explanation.
         }
         link: function(scope) {
            scope.resetModel = function() {
               scope.model.name = null;
               scope.model.email = null;
            }
         }
      }
}
