Cannot find a way to trigger binding with parameter

[Hermann]

I have a tag like this
<button data-bind="attr: { data-placeholder: Placeholder(512) }" />

Usually I trigger the change like this: model.trigger('change', { field: 'Placeholder'}) but this doesn't work in this case.

Could anyone help me?

Thanks!

Have found the Solution, thanks.

Hello Hermann,

I have prepared a Dojo example that demonstrates a similar scenario to the one described - programmaticaly triggering the view model change. With it, the change handler of the view model is being successfully executed with the following code:

<div id="example">
  <button class="k-button"
   data-bind="attr: { data-placeholder: Placeholder(512) }"
  style="width: 180px">Click me
  </button>
</div>

<script>
  var viewModel = kendo.observable({
    Placeholder: function(val) {
      this.trigger('change', { field: 'Placeholder'})
      return val;
    }
  });

  viewModel.bind("change", function (e) {
    alert("changed");
  });

  kendo.bind($("#example"), viewModel);
</script>
