bind:这种写法是否有bug?
<component-dropdown bindtoggleChange=“toggleChange”> 这个可以触发
<view slot=“dropdown-header”>这是头部</view>
<view slot=“dropdown-body”>这是内容区域</view>
</component-dropdown>
<component-dropdown bind:toggleChange=“toggleChange”> 无效没法触发toggleChange
<view slot=“dropdown-header”>这是头部</view>
<view slot=“dropdown-body”>这是内容区域</view>
</component-dropdown>
