Ui-template: sending msg through a function

I have tried all day to send a message through a function within the ui-template.

Here is a very basic example (one of many tries) inspired from the ui-template help and few other but to be frank I am not familiar with the scope concept and it is not working. Any help will be very welcome;

<md-button ng-click="myfunction(Clair)">Clair</md-button>
(function(scope) {
    function myfunction(name) {

Here are two ways to send messages

this.scope.action = function(value) { return value; }
<md-button ng-click="send({payload:action('clair')})">clair</md-button>

<!–– or with no script -->
<md-button ng-click="send({payload:'clair1'})">clair1</md-button>

Thanks, but how could I send the message within the function ?

My example does not make much sense but it is only to keep it simple and understand the principles

Here is a more complete example.
Note the following...

  • buttonName in the HTML is bound to scope.buttonName in the script
  • scope.func is set as a function & so is avaiable to call in ng-click as func(...)
  • When a msg arrives from node-red side, we can adjust scope.buttonName and it is immediately reflected in the dashboard button text
<md-button id="{{'my_button_'+$id}}" ng-click="func($event)">{{buttonName}}</md-button>

    (function(scope) {
        scope.buttonName = "clare";

        scope.func = function($event) {
            console.log("button clicked (you will see me in the console)");

        //watch for incoming messages
        scope.$watch('msg', function(msg) {
            console.log("msg received", msg);
            if (msg && msg.topic == "set-button-text") {
                // Set button text when msg.topic == "set-button-text"
                scope.buttonName = msg.payload;


Flow (use CTRL+I to import)...

To send a msg using your function the function needs to be a property in scope.

(function(scope) {
    scope.myfunction = function(payload,topic) {
        let msg = {
<md-button ng-click="myfunction('Clair

Thanks greatly!

Node Red is a great solution rather easy to learn and use but as soon as you move to template to improve the UI, it is another game...
I was trying to use (learn) HTML/CSS basic features but I guess I need also to better master the scope concept and Angular in general.
Any recommendation on the best way to do that?
