Yes. You are right that backspacing does not fire OnClientTextChange event. To catch when backspace is pressed you may use OnClientKeyPressing event for example:
In the Javascript function below 8 is the ASCII code of the Backspace button.
1.functionHandleKeyPress(sender, eventArgs) {
2.if(eventArgs.get_domEvent().keyCode == 8) {
3.alert("Backspace is pressed");
4.}
5.}
I've attached the full code as a .zip file.
If you have more questions, please let me know.
