(addChildren) : Cannot read properties of undefined (reading 'children')

[ngomezleal]

Hello, I need your helps.

I'm trying add new children in node, and I'm receiving the following error:
Cannot read properties of undefined (reading 'children')

I have the source data like example:
var datasource = {
'name': 'Lao Lao',
'title': 'general manager',
'children': [
{ 'name': 'Bo Miao', 'title': 'department manager' },
{ 'name': 'Su Miao', 'title': 'department manager',
},
]
};
.....
.on('click', function(event, data) {
debugger;
oc.addChildren($(this), { 'children': [
{ 'name': 'Tie Hua', 'title': 'senior engineer' },
]})
});

Line: 902
