Vis.js: Stay in addEdgeMode / Event after edge adding

I would like to stay in addEdgeMode in vis.js after adding an edge. Is there a way to achieve this?

My idea was to enable addEdgeMode again after adding an edge. Is there an event that is triggered after adding an edge? I know that there is the addEdge option in manipulation. However, this is triggered before the insertion.

you can enable the addEdge again right after the previous adding, like this:

manipulation: {
          enabled: false,
          addNode: function (data, callback) {
              // filling in the popup DOM elements
              console.log('add', data);
          },
          editNode: function (data, callback) {
              // filling in the popup DOM elements
              console.log('edit', data);
          },
          addEdge: function (data, callback) {
              console.log('add edge', data);
              if (data.from == data.to) {
                  var r = confirm("Do you want to connect the node to itself?");
                  if (r === true) {
                      callback(data);
                  }
              }
              else {
                  callback(data);
              }
              // after each adding you will be back to addEdge mode
              network.addEdgeMode();
          }

see the last row in this code example.

network.addEdgeMode();

this will enable the addEdge mode right after the callback fired.

see this example in plunker
