Info Request: What does updateValue actually do?

I'm using customBodyRender
```customBodyRender?: (value: any, tableMeta: MUIDataTableMeta, updateValue: (s: any, c: any, p: any) => any) => string | React.ReactNode;```

I am super curious on what exactly updateValue does and what the parameters are and how they function.

For some context, I am unable to pass lambdas into component attributes. So i have to create a function to have the code get called like so:
```
private handleOnChange = (tableMetaData: any, updateValue: any) => (e: React.ChangeEvent) => {
updateValue(e.currentTarget.value, tableMetaData.columnIndex)
}
```

but the update value gets called before the tableMetaData changes so my tableMetaData is always 1 "change" behind.
