当从输入框中删除最后一个字符时，事件不会在剑道网格和角度 5 中触发？

Question

我将多重过滤器应用于剑道网格，我的应用程序是在 angular 5 中开发的，这里的问题是，当从输入框中删除最后一个字符时，时间事件没有触发。如何解决这个问题。

例如，如果我在输入框 'alen' 中输入一些东西，dataStateChange 函数每次都会，同样的事情在删除 'alen' 最后三个之后删除那个时间函数将但第一个字符删除或删除它不会调用（dataStateChangefunction）。请帮助我任何一个。

添加[filter]="state.filter"到剑道网格选择器。我遇到了同样的问题，当我执行上述操作时它得到了解决。
