Refreshing Kendo UI viewModel - kendo-ui

Question

I have a very simply page at the moment. It has a first name input, last name input, and a list of names added. You can add your first and last name to the text box, press add. It adds it the peopleList I have and adds a new listItem with their name.
My issue is when I add to the peopleList in my code, it does not update the listView. I think I need to use observable, but I am not exactly sure how to do it. My list shows it has 25 items added to it after I click btnMany, which is how many it show have.
here is the body of my code:
<!--Load Some Data-->
<div id="peopleDefaultView"
data-role="view"
data-model="ViewModel"
data-layout="default">
<!--View-->
<input type="text" data-bind="value: firstName" id="fName" />
<input type="text" data-bind="value: lastName" id="lName" />
<a data-bind="click: addName" data-role="button" id="btnOne">Add</a>
<a data-bind="click: setValues" data-role="button" id="btnMany">Add Many</a>
<div style="margin-top: 10px">
People List:
<ul data-template="people-l-template" data-bind="source: peopleList" id="pList"></ul>
</div>
</div>
<!-- Kendo Template-->
<script id="people-l-template" type="text/x-kendo-template">
<li>
FirstName: <span data-bind="text: first"></span>
LastName: <span data-bind="text: last"></span>
<a data-bind="click: removeName" data-role="button" id="btnRemoveName">X</a>
</li>
</script>
And here is my script to go along with it
<script>
var ViewModel = {
firstName: '',
lastName: '',
peopleList: [],
addName: function (e) {
this.get("peopleList").push({
first: this.get("firstName"),
last: this.get("lastName"),
});
this.set("firstName", '');
this.set("lastName", '');
},
removeName: function (e) {
this.set("peopleList", jQuery.grep(this.peopleList, function (item, i) {
return (item.firstName != e.data.firstName && item.lastName != e.data.lastName);
}));
},
setValues: function (e) {
GetValueFromServer();
}
};
var GetValueFromServer = function () {
$.ajax({
type: "GET",
url: "GetPeopleService.svc/GetPersonById/",
data: {},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
response.forEach(function (person) {
ViewModel["peopleList"].push({
first: person.firstName,
last: person.lastName
});
});
alert(ViewModel.peopleList.length);
},
error: function (response) {
console.log(response);
}
});
};
var application = new kendo.mobile.Application(document.body);
</script>

There were a few things wrong with the code you provided, the most notably being that you didn't set the role for your <ul> element. You need to change it to have the attribute data-role="listview". You also can't use an <li> element as the root element for a listview template (KendoUI automatically takes care of this for you), otherwise you'll get an error when the list is bound.
Here's an example on JS Bin.
And here's the code:
<!--Load Some Data-->
<div id="peopleDefaultView"
data-role="view"
data-model="viewModel"
data-layout="flat">
<!--View-->
<input type="text" data-bind="value: firstName" id="fName" />
<input type="text" data-bind="value: lastName" id="lName" />
<a data-bind="click: addName" data-role="button" id="btnOne">Add</a>
<div style="margin-top: 10px">
People List:
<ul id="pList"
data-role="listview"
data-template="people-l-template"
data-bind="source: peopleList">
</ul>
</div>
</div>
<!-- Kendo Template-->
<script id="people-l-template" type="text/x-kendo-template">
FirstName: <span>#:first#</span>
LastName: <span>#:last#</span>
<a id="btnRemoveName"
data-role="button"
data-bind="click: removeName"
data-first="#:first#" data-last="#:last#">
X
</a>
</script>
...
var viewModel = {
firstName: null,
lastName: null,
peopleList: [],
addName: function (e) {
var me = this;
me.get('peopleList').push({
first: me.get('firstName'),
last: me.get('lastName')
});
me.set('firstName', '');
me.set('lastName', '');
},
removeName: function (e) {
var me = this;
me.set('peopleList', $.grep(me.peopleList, function (item, i) {
return item.first != e.target.data('first')
&& item.last != e.target.data('last');
}));
}
};
var application = new kendo.mobile.Application(document.body);
