Ionic select box how to detect value is changed?

I want to have classic style of select box so I use

<select class="box" name="al">
            <option value="all">all</option>
            <option value="a">A</option>
            <option value="b">B</option>

but in this case…how can I detect value is selected?
I don’t think I can use jquery…

I still don’t understand why ion-select is too much different than classic select box…
I don’t want to select any value from popup when I use selectbox.
