asp.net MVC - Dynamically Create Modal and set Event Listener

Question

I have bootstrap modal that gets created depending upon a search the user kicks off. The search returns an HTML table that is embedded in this new modal. Ultimately, upon the user clicking a row <tr> I would like that rows contents be passed into a form using jquery. My issue however is that i am not able to even get the click event to register to the <tr> of which I assign the class result-item. Im assuming this is because the table is created dynamically after the script is parsed but am unsure as to how to compensate.

View

<div id="IHS-Search-Results" class="modal fade" role="dialog">
<div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title">IHS Search Results</h4>
        </div>
        <div class="modal-body">
            <p>Select the well from the table bellow to populate form.</p>
            <div id="results-table"></div>
        </div>
        <div class="modal-footer">
            <div class="form-group">
                <div class="col-md-offset-2 col-md-10">
                    <input type="button" value="Close" data-dismiss="modal" class="btn btn-danger" />
                </div>
            </div>

        </div>
    </div>

</div>

@section Scripts {

    $(document).ready(function () {
        $('#submitModal').click(function () {

            var data = {

            }

Partial View - Returned to View from Controller

@model List<IHS_DATA_MANAGER.Models.IHS_API_SearchResults>

<table class="table table-bordered table-striped table-hover" id="r-table">
    <thead>
        <tr>
            <th class="text-nowrap">
                @Html.DisplayNameFor(model => model[0].API14)
            </th>
            <th class="text-nowrap">
                @Html.DisplayNameFor(model => model[0].EntityID)
            </th>
            <th class="text-nowrap">
                @Html.DisplayNameFor(model => model[0].ProductionZone)
            </th>
            <th class="text-nowrap">
                @Html.DisplayNameFor(model => model[0].LeaseName)
            </th>
            <th class="text-nowrap">
                @Html.DisplayNameFor(model => model[0].WellNum)
            </th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr class="result-item">
                <td id="API">@item.API14</td>
                <td id="EntityID">@item.EntityID</td>
                <td id="ProductionZone">@item.ProductionZone</td>
                <td id="LeaseName">@item.LeaseName</td>
                <td id="WellNum">@item.WellNum</td>
            </tr>
        }

    </tbody>


</table>

@section Scripts {


}

Again, it as if the click event never gets registered to the table row.

EDIT 2:

Ok, let's go on a higher level, change the handler to be:

$(document).on('click','.result-item',function(){
    alert(' clicked');
})

if that doesn't work then there is a different problem in your page (another JS error probably).

EDIT: Not sure if it is .table-item or .result-item, on the question you say .table-item but the actual row is .result-item, change accordingly.

As the table is created dynamically you need to use the .on method from jquery instead of .click, like this:

$('.result-item').on('click',function(){
    alert(' clicked');
})

or

$('.table-item').on('click',function(){
    alert(' clicked');
})

Tried this, still does not appear to be working. I am wondering if the fact that it is in a modal is affecting it? Or if the fact that iam using the Razor syntaz @section scripts{}...

This did the trick.. Do you have a guess as to why the previous did not?

Scope issues. Sometimes it helps going up a level just to make sure you are getting the correct element. Glad it helped.
