Distinct display text for each custom select box

[Balaji-Gopal]

I want to get distinct display text for each select box,Since I there is hard coded display text box as Select.. I need to change this so that for each and every custom select box has different display text.

Below code display text is not working for me, I am getting only the Select ....

<div custom-select="g.Name for g in vm.categories| filter:{Name:$searchTerm}" ng-model="vm.category" displayText="Category"></div>
