Problems with @click binding methods

[incacola]

When you bind an click Event on the Icons you get the following error message:

`
Property or method "del_User" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

On my side @click is not working at all.
