当我尝试使用ngIf运行方法时，获取“ERROR TypeError：jit_nodeValue_6（...）不是函数”

Question

I am trying to create a page that displays all of the values returned from my database. It should display all of the data in table rows using ngFor and it should replace the row with an ng-template full of input fields when the row is double clicked or when the edit button to the left of the row is clicked, by calling the editMovie() function in the .ts file.

The problem is that, when editMovie() should be called, I'm getting this error in the console.

ERROR TypeError: jit_nodeValue_6(...) is not a function

at Object.eval [as handleEvent] (MovieComponent.html:52)

at handleEvent (core.js:21673)

at callWithDebugContext (core.js:22767)

at Object.debugHandleEvent [as handleEvent] (core.js:22470)

at dispatchEvent (core.js:19122)

at core.js:19569

at HTMLButtonElement. (platform-browser.js:993)

at ZoneDelegate.push../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:421) at Object.onInvokeTask (core.js:16147) at ZoneDelegate.push../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:420)

I'm seeing this error thrown both when the row is double clicked (see line 20 of the html) and when the edit button is clicked (see line 52 of the html). This leads me to believe that the issue is with the .ts file. I also put a console.log() in the first line of editMovie() and it did not show, leading me to believe that the error is being thrown before editMovie is actually run.
