Ember could not get select value from template to component

I'm struggling with this. I would like to pass a select value from template to component. Here is my template

<select name="bank" class="form-control" id="sel1" onchange=>
        
        <option value=></option>
        
        
      </select>

And here is my component

  actions: {
  updateValue: function(bank) {
  this.set('bank.id', bank);
  },
  login() {
    console.log(this.get('bank.id'));
  }

And i've got this beautiful error : Property set failed: object in path "bank" could not be found or was destroyed.

Any idea ? Thanks
