 OnPush change detection instructs Angular to run change detection for a component subtree **only** when:
 * The root component of the subtree receives new inputs as the result of a template binding. Angular compares the current and past value of the input with `==`
-* Angular handles an event _(e.g. using event binding, output binding, or `@HostListener`)_ in the subtree's root component or any of its children wether they are using OnPush change detection or not.

 Disable checking of a binding expression by surrounding the expression in a call to the [`$any()` cast pseudo-function](guide/template-expression-operators).
