I am preparing a custom ui node. In this node, I want to process the data on the ui side as soon as the data comes from the socket, but in the beforeemit property, it is triggered only when data from another node arrives. In what other way can I use this data live on the ui side?

```auto
var done = ui.addWidget({
            node: node,
            order: config.order,
            .....
            beforeEmit: function(msg){
              //it is triggered
            },
            initController: function(){}
})
node.server.getListenSocketData().thenAgain((data) => {
            try {
                if (data) {
                    var resultModel = JSON.parse(data)
                    if (node.id == resultModel.id) {

                        node.send({ payload: node.buttonValue })
                      
                    }
                }
            } catch (err) {
                console.log(err)
            }
        });

```
