Issue description

Current behavior:

I have a stepper within a window that I use for a setup wizard. The first form has several nb-selects whose options are rendered. The third form also has an nb-select. However it's options aren' rendered. When the window opens, the backend call for the data needed by the third form is loaded, and I display it in the console but on reaching the third form, no options are available to select from.

I used an observable to have the data load only when the second form is successfully submitted. Works with a normal select but still not with ng-select.

Expected behavior:

When the third form is loaded, the nb-select should have data bound to its options.

Steps to reproduce:

• Create a component A, having a stepper.
• Create two components, B and C, each having a form and nb-selects.
• Include the forms in component A
• Have both forms call a service in the back end to get data.
• Display A in a window
• Start the application and have the window displayed
• Move to form B
• Try to select an option from the dropdown

Same issue here. Interestingly the select will also stop working after moving back in the stepper.
I can also confirm that it seems to be broken when used in tabs and accordion also :s
