У меня есть рабочая версия вашего кода здесь:
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
boxSelectionEnabled: false,
autounselectify: true,
style: [{
selector: "node",
css: {
"label": "data(id)",
"text-valign": "center",
"text-halign": "center",
"background-color": "data(faveColor)"
}
},
{
selector: "edge",
css: {
"curve-style": "bezier",
"control-point-step-size": 40,
"target-arrow-shape": "triangle"
}
}
],
elements: {
nodes: [{
data: {
id: "a",
faveColor: "#2763c4"
}
},
{
data: {
id: "b",
faveColor: "#37a32d"
}
},
{
data: {
id: "c",
faveColor: "#37a32d"
}
}
],
edges: [{
data: {
source: "a",
target: "b"
}
},
{
data: {
source: "a",
target: "c"
}
}
]
},
layout: {
name: "dagre"
}
}));
cy.ready(function() {
cy.dblclick();
});
var nid = 0;
cy.bind('dblclick', function(evt) {
cy.add({
group: 'nodes',
data: {
id: nid,
faveColor: 'red'
},
position: {
x: evt.x,
y: evt.y
}
});
nid++;
});
cy.bind('click', 'node', function(evt) {
console.log('node clicked: ', evt.target.id());
});
body {
font: 14px helvetica neue, helvetica, arial, sans-serif;
}
#cy {
height: 100%;
width: 100%;
float: right;
position: absolute;
}

Я использовал метод cy.on () / cy.bind (), который, кажется, работает с вновь добавленными узлами:)
