Changing text with jquery and jquery mobile

JavaScript
1

I have a some jquery mobile code on my page and I want to change the text within them using jquery for example I want to change the text within the header. and add content to the list.

<div data-role="page" data-add-back-btn="true" id="venues">
			<div data-role="header">
				<h1>Test</h1>
			</div>
			<div data-role="content">
			<ul data-role="listview" data-filter="true" data-filter-placeholder="Search list..." id="customAlgorithm">

usually you add content to the id of the div however am not sure what the id is for both the list and the header is in the code above.
