@bind
From Documentation
Syntax
@bind( [EL-expression] )
Description
Target Attribute: all (except viewModel, validationMessages, form)
Purpose: Specify that binder can both save and load data
It's like a shortcut annotation that combines both @save and @load . When your saving and loading don't depend on different condition, it's suggested to use this annotation.
Example
<textbox id="t2" value="@bind(vm.user.account)" />
<doublebox id="pbox" value="@bind(vm.selected.price)"/>
<datebox id="sdbox" value="@bind(vm.selected.shippingDate)"/>
