I have created my own widget to be called in tree views this way:

<field name="selected" widget="toggle_switch"/>

The field selected is of type boolean. I created the widget class extending the Column class:

var ListView = require('web.ListView');
var ToggleSwitch = ListView.Column.extend({
   ...
})

And I have registered it this way:

var core = require('web.core');
core.list_widget_registry.add('field.toggle_switch', ToggleSwitch);

And it is working, but now I want to modify the value of the selected field each time the user clicks on the main element of the template I made for the widget.

The problem is that I am not able to do that. It seems that events dictionary is not available for the Column class, and I cannot use something like this.on('click', this, this.on_click); or this.$el.find(...), as this brings only the field data.

Can anyone help me? Should I inherit from other classes to use events in my widget (in fact I have tried, but in every case my Qweb template just disappeared from the tree view...)?
