    I have an MVC4 application and am trying to use the Listview using the MVC wrappers. I am using an edit and a view template. 
     If there are 4 items in my list and I add a new one the Create action is called 5 times, thus 5 records get added.

    I am using the latest Q2 trial version. However I previously had downloaded the beta trial version which included an MVC example project which showed the exact same behavour. Is this a bug?   
    (Note the same issue occurs for other actions as well)
    <div class="k-toolbar k-grid-toolbar">
        <a id="addRoleButton" class="k-button k-button-icontext k-add-button" href="#"><span class="k-icon k-add"></span>Add new Role</a>
            .DataSource(dataSource => dataSource           
                .Model(model =>
                        model.Field(f => f.ProjectId).DefaultValue(Model.ProjectId);
                        model.Field(f => f.Title);
                        model.Field(f => f.Description);;
                .Events(e => e               
                .Create(create => create.Action("createRole", "Project"))           
                .Read(read => read.Action("getRoles", "Project", new { projectId = Model.ProjectId }))
                .Update(update => update.Action("updateRole", "Project"))   
            .Events(e => e

    View Template
    //View template
    <script type="text/x-kendo-template" id="rolesList">
        <div class="roleView" >
            <div> ${Title} </div>
            <div> ${Description} </div>
            <div class="edit-buttons">
                <a class="k-button k-button-icontext k-edit-button" href="\\#"><span class="k-icon k-edit"></span>Edit</a>
                <a class="k-button k-button-icontext k-delete-button" href="\\#"><span class="k-icon k-delete"></span>Delete</a>

    Edit template
    @model iProjX.Models.RoleModel
    <div class="roleView" id "newRoleForm2" >
        @Html.HiddenFor(model => model.ProjectId)
        @Html.HiddenFor(model => model.RoleId)
        <div class="editor-label">
            @Html.LabelFor(model => model.Title)
        <div class="editor-field">
            @Html.TextBoxFor(model => model.Title, new { style = "width:99%", maxlength = 100 })
            <span data-for="Title" class="k-invalid-msg"></span>
        <div class="editor-label">
            @Html.LabelFor(model => model.Description)
        <div class="editor-field">
            @Html.TextAreaFor(model => model.Description, new { style = "width:100%; height:100px"})
            <span data-for="Description" class="k-invalid-msg"></span>
        <div class="edit-buttons">
            <a class="k-button k-button-icontext k-update-button" onclick="updateClick()" href="\\#"><spanclass="k-icon k-update"></span>Save</a>
            <a class="k-button k-button-icontext k-cancel-button" href="\\#"><span class="k-icon k-cancel"></span>Cancel</a>

    Can you provide the code for your controller?  The action method should be caught there for example, ...
    public ActionResult ContactResearch_Read([DataSourceRequestDataSourceRequest request)
                return Json(GetContactResearch().ToDataSourceResult(request));         

    The _Create would be just another line item here and should not call the read method. Otherwise, are you
    returning the entire list back or just the item that you edited. I believe it only expects the item that was
