Error when calling directive

Hello, I get the following error:

```
Uncaught TypeError: binding.value is not a function
    at HTMLLIElement.eval (index.js?2993:6:1)
    at compare (base.min.js?86dd:3:1)
    at eval (base.min.js?86dd:3:1)
```

This is the way I'm calling it:

```
v-hover-intent="{ change: productsHover, value: 1 }"
```
