Collection-repeat not showing list. It Shows scroll but not data

I am using below code for my app :

<ul class="list card">
	<div class="item item-divider" style="font-size: large;">
		<b>Upcoming Schedule</b>
	<li class="item"
		collection-repeat="schedule in Schedules | filter:upSearch">
		<div class="row" style="padding: 0px;"></div>

Here row contains some schedule info.
when i am using ng-repeat instead of collection-repeat it works perfectly but slowly.
Please help me to resolve this.
