Use ng-options instead ng-repeat

You need to use ng-options with ng-model.

In many cases, ngRepeat can be used on elements instead of ngOptions to achieve a similar result. However, ngOptions provides some benefits such as reducing memory and increasing speed by not creating a new scope for each repeated instance, as well as providing more flexibility in how the 's model is assigned via the select as part of the comprehension expression.

 <select ng-options="items for items in objectList" ng-model="primaryObjectId"></select>

See example

See this example to get items based on value of option item.

Set drop down item based on id. See example
