create a place to store references to each dropdown, just an object literal or something, make each entry initially null , | |
when the success function of each async returns set up the dropdown and stick it into the right spot on the object literal, | |
then call a function at the end of each success that checks the object literal, | |
if there's any null values it does nothing, otherwise everything is done & it starts setting up the datatable, | |
I don't know a ton about how to set up cell editors like that so it's entirely possible you could be setting up the DT while the async calls are waiting |
