Ember select element - unable to capture on change event

Ember question - still getting used to Ember, but making progress. Here's my issue: I have a template which references a component; the component contains a select element. The select element displays properly, and I want to update the contents of another select element based on the selection in the first element. However, I have not been able to capture the on change event of the first select element. Here is the component code containing the select: {{view "select" content=types value=selectedtType selection=selectedtType prompt="Select Type..." }}

So I'm not sure how to reference the on change event in the component template, or where the function itself should go - the component's component.js file, or in the route.js file of the parent template. I've done much research on this, but haven't been able to make it work yet. Any help would be appreciated. Thanks.
