##<iron-input>
`<iron-input>` adds two-way binding and custom validators using `Polymer.IronValidatorBehavior`
to `<input>`.
### Two-way binding

By default you can only get notified of changes to an `input`'s `value` due to user input:

`iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used
for two-way data binding. `bind-value` will notify if it is changed either by user input or by script.

<input is="iron-input" bind-value="{{myValue}}">
### Custom validators
You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`.
<input is="iron-input" validator="my-custom-validator">
### Stopping invalid input
It may be desirable to only allow users to enter certain characters. You can use the
`prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature
is separate from validation, and `allowed-pattern` does not affect how the input is validated.
<!-- only allow characters that match [0-9] -->
<input is="iron-input" prevent-invalid-input allowed-pattern="[0-9]">
