Custom Visual fetchMoreData function not responding

[Anonymous]

I have a custom visual with 80,000 rows of data i want to input into it. I call fetchMoreData in the update function and nothing happens, the update function is never called and i dont see any new data in the logs.

 this.host.fetchMoreData(true)

Interestingly initaly my data has no segments in the metadata, I would have thought there would be as there is more then 30,000 rows in the data set.

Any thoughts on why the function isnt updating anything is greatly apprecated.

I needed to initilize the host in the construtor

this.host = options.host;
