My HTML helper includes a textBox that looks like this:
@Html.TextBox("txt1") <br />
I am interested in triggering a javascript onchange event on this textbox. Can this be accomplished, or would it be better to use an HTML input type instead?

To add HTML attributes to a TextBox using the htmlAttributes parameter in the Html helper method, follow this format:
@Html.TextBox("txt1", null, new { onchange="..." })
For more information, refer to: InputExtensions.TextBox Method
As mentioned in the provided link:
The htmlAttributes parameter is an object containing key/value pairs representing the attributes specific to the rendered HTML element.
If you possess the identification for this specific textbox, Jquery can help you link the event directly to the textbox.
$("#textboxid").keydown(function(event) {
alert("Hello!");
});
It's important to note that I have opted for the Keydown event. Alternatively, you could utilize press or up events.
Another option is to establish the binding within the ready event.
$(document).ready(function(){
$("#textboxid").bind("onchange", yourfunction);
});
