If binding handler is not defined, type injection will fail

[tscpp]

The child context should default to ChildBindingContext<unkown, unknown>. All of the referenced variables in the view exists in ViewModel. This will lead to all variables in child bindings not be defined.

<!-- ko-viewmodel: import default from './window' -->

<div class="window" data-bind="draggable: windowdrag">
	<div class="window--window-wrapper">

		<!-- ko if: showTitleBar -->
		<div class="window--title-bar">
			<div class="title" data-bind="text: title, drag: windowdrag"></div>
			<div class="controls">
				<button class="no-ui control control-hide">
					<img src="/icons/minimize.svg">
				</button>
				<button class="no-ui control maximize">
					<img src="/icons/maximize.svg">

		<!-- ko if: component -->
		<div class="window--content" data-bind="component: { name: component, params: { windows: windows } }"></div>
